Critical error after WP6.6

@ollieknights thank you so much for this info. When i rename it to disable it, do i simply just install the previous verion and thats it? what happens to the renamed plugin?

@jbatey yep! Simple as that. Reinstall the old version and you are done.

For me it overwrote the old renamed version and removed it. But if not you can delete the renamed version from the FTP when you are up and running again.

Same issue here! Version 2.6.24 crashes WordPress 6.6!!

Thank you all for reporting this. We’ve just released an update to correct the error. It had nothing to do with WordPress 6.6. The version of the release that got pushed to WordPress had a set of library files that somehow weren’t updated/synced with our local development version (and so had a different version number), causing the not found error you were getting.

@jaysupport thanks for the update and the new release. Works perfectly.

Just got an e-mail from Five Star support where they apologized an told me they fixed it.

I tried ist and voila: version 2.6.25 works!

I cannot enter to admin panel due to this error message. I went to FTP and disabled all plugins but still have the same error message. How can i downgrade in FTP?

Same here, critical error. I went to PHP and deactivate all plugins but still have no acces to the admin panel. How to fix this?

You haven’t disabled the plugin since it still refers to an error in the plugin “/mivino/wp-content/plugins/restaurant-reservations/lib/…” so you should delete the plugin and install the new version. This has nothing to do with wordpress 6.6 as the author replied so just get rid of the old plugin and your wordpress should be running again. I am running without problems wordpress 6.6 and the newest plugin version.

Hi @vivanda

Thank you @asle. ?? The issue was indeed patched, but it looks you (@vivanda) are still trying to run the 2.6.24 version. Make sure you are updating to version 2.6.26. Or you can easily just do as asle suggested and delete the plugin and install it again as a new plugin.
