Admin area of Revolution Slider not working

[jprgrant]

My site is running X theme with Revolution Slider. Recently, Rev Slider’s admin area stopped working - when I click on Rev Slider in the left-hand menu, I just get a blank screen (with the sidebar menu showing). The front-end part is still working fine and showing the slider properly.

I’m not sure where to look to resolve this - I had a look on the server, but there’s nothing in the error log.

I’m scared to reinstall Revolution Slider in case it deletes my existing slides - is this likely to happen? Is there a way to back them up beforehand?

Thanks!

Hi Jamie,

Thanks for writing in! Since you’re getting a blank screen, could you please try enabling WP_DEBUG mode by following this guide (https://codex.wordpress.org/WP_DEBUG) and then re-visit Recolution Slider backend to see if there’s any PHP errors that describes your issue.

Deleting your Revolution Slider could lose your existing data. You can download all files from your Themeforest account

Then when you unzip it, you should be able to locate revslider.zip plugin under “/x_package/extensions/” directory.

Unzip revslider.zip plugin file and upload it into your “/wp-content/plugins/” directory. This will replace and fix any missing or corrupted files in your Slider Revolution plugin.

If you’re still having issues, please provide us with your WordPress login credentials along with your FTP credentials in a secure note to check your issue further.

Let us know how it goes.
Thanks!

Thanks. I’ve enabled Debug, and got the following error (there were other similar errors, but this was the first that seemed to be related to RevSlider):

I’m not sure what I need to do to fix that.

I’ll try downloading the files from Themeforest - will that lose my existing slides? Or is it only reinstalling that would lose the data?

Hi Jamie,

You do not have to uninstall Revolution Slider. You just need to login through FTP then go to wp-content/plugins then delete the revslider directory from there and place the revslider directory you have just downloaded in the plugins directory.

Hope this helps.

That seems to have fixed it! Thank you!

You are most welcome!
