Permission error for backend users / PHP warnings in log

[awi-linkgroup]

Hi,

Using TYPO3 11.5.39 / ai_translate 2.1.2

1. When trying to translate a page as a backend user (not admin), we get an alert:
1: Attempt to modify table 'localization' without permission

I tried to find out where to set permissions, but didn't find.
What is this alert about? The translations are working properly.

2. in the log file I got a bunch of PHP warnings:
Core: Error handler (BE): PHP Warning: Trying to access array offset on value of type null in /var/www/html/public/typo3conf/ext/ai_translate/Classes/Hooks/TranslateHook.php line 162 Core: Error handler (BE): PHP Warning: Undefined array key "pages." in /var/www/html/public/typo3conf/ext/ai_translate/Classes/Hooks/TranslateHook.php line 356 Core: Error handler (BE): PHP Warning: Undefined variable $field in /var/www/html/public/typo3conf/ext/ai_translate/Classes/Hooks/TranslateHook.php line 159 Core: Error handler (BE): PHP Warning: Undefined global variable $_SESSION in /var/www/html/public/typo3conf/ext/ai_translate/Classes/Hooks/TranslateHook.php line 120 Core: Error handler (BE): PHP Warning: Undefined array key "srcLanguageId" in /var/www/html/public/typo3conf/ext/ai_translate/Classes/Hooks/TranslateHook.php line 120 ...

Are the permission alert and the php warnings related?

Thank you.
