Hello,
Before explaining my problem I want to say that I tried to solve it with what's on other topics (increase memory in wp-config or change the vibe-customtypes plugin). But none of this worked, I have deleted and attempted to reinstall the site 7 times (differently each time) but nothing works.
Does someone could help me because it's five hours that I work on it and I'm starting to lose patience!
Thank you.
Best regards.

Hello,
I fixed the problem after uninstall and re-install wordpress, plugins and WPLMS 11 times. I do not really know what has to adjust it but it worked.
Thanks for your help.
Thanks for updating. It would be great if you could also raise a ticket with your host so that in future the issue can be avoided.
