Hello Ofi Khan,
Thanks for your answer.
The site https://www.randouveze.fr is running under Joomla 4.2.3, Helix Ultimate, php 8.1.
I cannot go ahead to work with SP Pagebuilder 4.0.5 mainly due to the narrow width of the text block editor which is not convenient when I have to work with large tables. Therefore I decided to come back to SP PB 3.8.9 which is much more convenient to work with.
I installed this version and the installation ran perfectly but an error 0 occurred when calling the welcome page (Accueil) on the front end.
I invite you to try the installation of SP PB 3.8.9 to see what is going on.
I have a complete back up of the site just in case.
By the way, is it normal that SP PB locks the data base "table xxxxx_sppagebuilder" when used?
