Gateways page problem on backend

Hello...
Today i tried to check the paypal gateway on my site, but when i click on Gateways admin menu item i get...

An error has occurred.

0 Call to a member function get() on null

Payments work fine

Can you please advise?

Please make sure that you have latest versions of Joomla, CB and all add-ons.
For CB and add-ons, go to Plugin management -> Install & update and click "Update All" (of course backup first as usual).

Does that solve your issue ?

If not, please state versions of Joomla, PHP and Mysql.

Thank you for your reply...

Community Builder Updates: Your install is up to date.

Database Type mysql
Database Version 5.7.36
Database Collation latin1_swedish_ci
Database Connection Collation utf8mb4_general_ci
PHP Version 7.4.25
Web Server Apache
WebServer to PHP Interface cgi-fcgi
Joomla! Version Joomla! 3.10.0 Stable [ Daraja ] 14-August-2021 11:55 GMT
Joomla! Platform Version Joomla Platform 13.1.0 Stable [ Curiosity ] 24-Apr-2013 00:00 GMT

Check this:
CB -> Tools -> Check Community Builder Plugins Database

And if there are errors, click the fix button.

If there are no errors on fixing, but you still see the error, please enable Joomla Configuration -> System -> Debug site
It should display more information.

Or the fix gives errors with row sizes, please check this possible issue with collations:

If that doesn't fix it or you found the issue, please report back in all cases

Thank you for your reply. Database gives no red lines to be fixed. Enabled debug and i got some errors. Please check if they are related...

I'm not able to reproduce this issue. Which gateways did you have configured ? and which were enabled ?
