I use centreon every day, and the extension manager has worked very well so far.
But when I go to this page now, it appears empty without any info :

I've already tried to fix it via other help pages, but to no avail. I've updated php, modified the conf, cleared my browser and centreon cache, but nothing works.

I'm on version 23.04.0.

Please, if you have even one lead, don't hesitate to share it with me. If you have any questions, please don't hesitate to ask.
