Critical error after WP6.6

We are having a critical error too.

Same for us too, WP 6.6 and Restaurant Reservation 2.6.24

The error occurred at my website last night with WordPress 6.5.5 and remained after upgrading to 6.6.

Because of the timing I assume it is the same error.

Same here.

Downgrade to previous version and the site works again:

Thanks, downgrading worked for me, but the correct link is of course https://downloads.www.ads-software.com/plugin/restaurant-reservations.2.6.23.zip

@krichel – lifesaver! This has worked perfectly.

We are having the same issue with

Fatal error: Uncaught Error: Class “sapLibrary_2_6_21_rtb”

….on the

/home/nkdzqjih/sites/mysitecom/wp-content/plugins/restaurant-reservations/lib/simple-admin-pages/simple-admin-pages.php

line.

That’s WordPress for you – cant complaint about a house of cards that’s built on good faith and volunteer work.

Will await a patch.

Thank you for all your hard work!
Same mistake here, thanks in advance for the correction.

Same issue here.
Downgrade fixed it.
Turned off auto update for now.

how do i ‘downgrade’????

and if i do ‘downgrade’do i lose any existing booked data?

You will not loose your booked data. The best option is to FTP to your site and replace the version with the older one.

I fixed like this restaurant-reservations->includes->Settings.class.php. line 1063 ‘version’?????? => ‘2.6.21.rtb’, to ‘version’?????? => ‘2.6.21,

mate, no idea what means what so ever. surely they will update this asap?

alexei are you able to please help me get this working?

@jbatey Some (like cPanel) will allow you FTP access to your file structure to tinker. Handy link below:

How to Deactivate All Plugins When Not Able to Access WP-Admin (wpbeginner.com)

Basically you are going to rename the plugin in your file structure to disable it.

This restored front end access to my website.

I then returned to the plugins page on my website and used the upload zip file for the previous version:

https://downloads.www.ads-software.com/plugin/restaurant-reservations.2.6.23.zip

I then activated that and to my relief it a.) worked b.) kept all my bookings and settings such as email templates etc.

Good luck!
