Page builder somehow broken

Support
#1

Hello,

The preview mode in the page builder (using Theme Pro) is somehow broken). Could you please help me to fix it?

Preview of the Page builder: https://mandtis.fr/wp-content/uploads/2017/08/Preview-Page-Builder.jpg

I have been working on the performance optimisation of a website, which might have broken something but I am not able to find out what might be causing the issue. Note that I also notices some strange things in SEMrush by working on the SEO and some links or images are indicated as 403 errors (but this is different everytime I run the analysis in SEMrush, which make me think the problem might come from a plugin or a setting or anything else).

I would really appreciate your help as I could not fix it after spending some time on it.

Hi there,

Thanks for writing in! Upon checking your site, I see the following error.

wp-lists.min.js?ver=4.8.1:1 Uncaught ReferenceError: ajaxurl is not defined

Usually, wp-lists is related to widgets, would you mind removing your widgets and test it if it’s going to fix this issue? I could do that but please backup your site first.

If your hosting has a built-in cache system, then please make sure it’s inactive while you’re testing.

Also this issue could happen if your WordPress core files are corrupted. In that case, you can try re-installing your WordPress core files. You can check the following guide here (https://codex.wordpress.org/Updating_WordPress#Step_1:_Replace_WordPress_files)

Thanks!

Thanks for the quick response.

I don’t know what you mean by “removing the widget as I haven’t done anything with it today” and it was just working fine before. As I said I have been working on improving the performance of the website. But as I am not really experience with it, I might have done something that has created the issue.

I have done the following:

  • changing the DNS to use Cloudfare CND (it was done on Friday though)
  • activating the plugin W3 Total Cache (which was install on Friday and worked fine)
  • Testing plugins and desactivating them seeing no improvement in the perfermance.
  • the plugin autoptimize has been added on Friday as well

The problem must come from one of these things but I realy can’t tell how to fix the issue.

I have done a backup of the site. Please go ahead with the changes you think that might fix the issue.

Thanks,
Antoine

I managed to solve the problem. It came from parameter in Cloudflare (minifysing the CSS).
