Update to 1.2.1 breaks wp-admin

got the same issues after update to 1.2.1 – had auto update set for the plugin and discovered this morning I could no longer get to the back-end of the sites that ran the update.
Two of my sites using the plugin reported the error to me via email and offered a link for recovery mode so I could disable the plugin, another site just hung on the wp-admin page so had to disable the plugins via the database…

Here is what WP sent via email about the plugin issue

Error Details
=============
An error of type E_ERROR was caused in line 438 of the file /path/to/documentroot/public_html/wp-content/plugins/themify-popup/includes/themify-metabox/includes/themify-metabox-core.php. Error message: Uncaught Error: Call to undefined function themify_enque() in /path/to/documentroot/public_html/wp-content/plugins/themify-popup/includes/themify-metabox/includes/themify-metabox-core.php:438

Line 438 in themify-metabox-core.php does indeed try call themify_enque as well as the six lines following it too.
Did a search for that function within the entire WP directory and the only reference to that is in those lines in themify-metabox-core.php, so the function is completely missing from the plugin…
Interesting that it only affects the the back-end, the front end still works fine, including the popups…

Hopefully an update will be released quickly to address this…

Same problem. I hope they resolve as soon as possible. Unfortunately you can’t even download the previous version of the plugin.

I still have a site running 1.2.0 and have zipped up the plugin directory.
You can download it here – zip file and tar-gzip

As far as I’m aware you should be able to replace your current directory with the contents of the compress file I’ve made of my directory…

@rhysmcw Ok, done. Thank you very much!

Hi!

Our sincere apologies for this issue. It was caused by an issue in our deploy, the plugin has now been updated with the fix.

Thank you for reporting the issue and for your patience! If you come across any issues with the plugin, please do let us know.

@shazdeh I tried this latest version but instead of breaking the control panel, everything else breaks, as well as the actual site: the pages, for example the homepage, are all busted. I was forced to go back to version 1.2.0 once again.

That is weird. I just tried the latest release, backend and frontend are all fine. Would you happen to catch what error it was generating? With debugging enabled (please see: https://www.ads-software.com/support/article/debugging-in-wordpress/#wp_debug) WP displays the error messages, that can help determine what is causing the issue.

For myself, it′s working again. Thanks!

@shazdeh May you′re willing to allow download of previous versions of your plugin by WP.org?

Two of my sites did the auto update overnight, just re-activated the plugin, fontend and backend work fine for me.
Thank you for the quick turnaround on a fix.

@aneises That’s good to know, thanks! About adding earlier versions to wp.org, definitely. For future updates we’ll make the earlier version available for download.

@rhysmcw Thanks for the confirmation.
And again, apologies for the error it caused.
