Unable to edit any page - The preview could not load due to the iframe response being incomplete. This is most often related to a plugin conflict, or customizations introducing a PHP error

Hello -

I am getting this error using Cornerstone whenever I try to edit ANY page.

The preview could not load due to the iframe response being incomplete. This is most often related to a plugin conflict, or customizations introducing a PHP error.

Origin URL: https://workingwithfaculty.com

Preview URL: https://workingwithfaculty.com/

I have checked general settings and both urls are set to https and the url is the same.

I have gone through 4 of these threads and nothing is exactly the same or working when I try it.

I have installed version 5.4.8.3 of the Slider Revolution that came with the X theme - I am currently using the X - Child Theme.

These are the only entries in my global css under X > Launch > Options > CSS:

.x-navbar .desktop .x-nav > li > a:hover, .x-navbar .desktop .x-nav > .x-active > a, .x-navbar .desktop .x-nav > .current-menu-item > a {box-shadow: none !important;}
.my-blockquote1 {
font-size: 24px;
}

The first code is to turn off the bar that hovers over the menu when I move my mouse and stays over the current page I have selected. That was recommended by Apex Support and that worked beautifully.

The second bit of code was to change font sizes in my block quotes on the Programs/Services page. Only one entry in the global css as my-blockquote1 and then for every block quote on that page, I used the same in the Class ID. I didn’t have to change it to anything else.

BLOCKQUOTE FONT SIZES

This:
my-blockquote1 (in the Class ID field of the blockquote in question)

Then this:
.my-blockquote {
font-size: 24px;
}
(in the global css under X > Launch > Options > CSS

Right now, I am unable to edit any page. I could really use the help asap.

Credentials are in the secure note.

Thank you!

Susan

Hi Susan,

Thank you for writing in, it seems your child theme is being nested. Please switch to parent X theme (Appearance > Themes) and see if that resolves the issue.

If it does, please move your x-child theme under the /wp-content/themes/ directory. Currently it is setting under /wp-content/themes/x-child/x-child/ you can do this via cPanel’s File Manager or FTP.

Let us know how it goes,
Cheers!

Hello -

I took a full backup before doing this. I’m not sure how this happened as I updated to the latest version of the X theme and X - child theme not long ago. The last web administrators (two of them) that I had did not update the website since v1.1. Did X change directory structures as they developed newer versions?

I’m confused.

I will attempt this change to the X theme in 15 minutes and see if it corrects other changes I’ve seen recently as well. If it doesn’t, I’ll move the directory over. Would it hurt to just make a copy or should I cut and paste?

Thank you and Cheers!

If it messes things up, I’ll restore to the backup I just took.

Updating the theme from the child theme to the X theme didn’t resolve the issue. It seemed to resolve itself before I made changes.

There is an issue I’m still having with editing the about-susan page. It very well may be related.

If you visit the page: https://workingwithfaculty.com/about-susan/
you’ll see there is content including About Susan, Susan’s Professional Background, and Susan’s resume (with a lowercase r).

However, if you go to the X - Cornerstone editor to edit the page, it comes up with an empty page, just the header and the footer. I have verified the path and the name of the page is correct (about-susan).

Ideas?

One more thing I wanted to add. I don’t believe the x-child theme’s to be nested. The contents of both are different. Take a look.

I’m happy to give you credentials to get into the hosted cpanel filesystem if you like.

In the meantime, here are the credentials for the Wordpress site again.

Hello Susan,

The style url of the child theme should only be:

https://workingwithfaculty.com/wp-content/themes/x-child/style.css?ver=6.5.6

And in your child theme has been installed incorrectly.

This means that the child theme’s x-child folder was installed inside another x-child folder. You will have to correct this first by removing the other folder.

Please let us know how it goes.

Oh my gosh. Was that the fault of the installer?

Okay, I will make the change today.

To be clear, do I just follow your original instruction and move the folder?

Would it be okay to copy the folder and leave the existing folder or will that cause the software confusion?

Thank you in advance!

Hi Susan,

It’s not possible to have two folder with same name. I recommend renaming your first x child folder, then move/copy your second x child folder to the main theme folder.

Thanks!

In your instructions, which is the first x child folder and which is the second x child folder? I’m confused.

I made the change. I took it to mean that I should rename the higher level x child folder (I renamed it to renamed first x-child) and then moved the nested x-child up directly under the themes folder.

Did I do the right thing? Can you please check the integrity of the structure now?

I had to go into the Appearance > Themes to activate the X Child theme.

Performing this action altered some of the pages formatting. Such as this:

I’m unable to resize the logo font in the header.

And the background of the menu dropdowns have changed as well!!!

When entering the Theme Editor through Appearance > Theme Editor, it says v1.0 ???

Help!!!

Hello Susan,

Thanks for updating the thread. :slight_smile:

Yes, as per the screenshot the structure of the themes looks fine.

I checked the website and it seems that parent theme is now active theme. Regarding the background color change, please make sure that if you have made the changes in child theme using custom CSS then the correct child theme is in activate state. If changes are made in a different theme theme (as now there are couple of child themes in server) and that particular child theme is not active then changes won’t reflect on front end.

Yes, that’s fine. Child theme usually is version 1.0. It’s the parent theme that gets the update from Themeco and that will have the relevant version number depending on the development cycle.

Thanks.

I just wanted to followup and let you know that the last list of problems that I had above, all showed up when I set the default theme to the Child Theme after changing the nesting as suggested.

After I set the default theme back to the primary X Theme, the other problems went away except for the Top Bar with the physician’s name. I went into Options in the Cornerstone editor and was able to set the font size from there. The color and font were inherited through CSS settings.

I wanted to thank you for hanging in there with me to get this resolved!

We are very much obliged to you,

Cheers!
