After upgrading to Joomla 4 pictures in blog doesn't appears in folder mode

I think I found the reason of the problem.
I am using AdminTools and in the setting of the htaccess maker, I just added the following exception in the server protection part/ Allow access to these files section:
components/com_flexicontent/librairies/phpthumb/phpThumb.php
And now it works fine even with resize.

I hope this helps

thanks for return
