Can't add, edit, delete content

[Nibel]

Hello,

I had no Internet connection since 4 months, then it's come back and I update my webserver and Bluedit to 3.15.0 but now I can't add, edit or delete my Bluedit content from my admin panel...

My website is online and working :
https://blog.nibel.fr/

I've no JS error in console, I tried to delete all plugins in bl-plugins but it does not solve the problem.

I enable debug mode but it does not create the file in bl-content.

It's probably a right problem but i don't know where exactly...

Someone have an idea please ?

This could be. Try to install Bludit in another directory, and look if this works.
