I need your help, I am a beginner and I don’t understand much of what is going on. I woke up one morning and the content of my blog had disappeared (from the site and from my dashboard). Articles, pages, images, and menus have all disappeared and I get the following error Content not found. The content you are looking for could not be found. Only remains the structure of my theme and widgets. Fromm y dashboard, I can access comments but they are not link to anything. I have not done any major modification before the issue, or maybe a plugin update that I can remember. However, after the issue, I have tried deactivating them all and I have deleted two of them (wpbiographia and nextgengallery).
I have restored the FTP backup and the database one (it had disappeared) to the best of my abilities. I tried two different FTP backup from a different date to see if there was a difference. I went into phpmyadmin and in the tables, but there was no error anywhere and no need to repair.
I have updated the theme. I have changed the theme to see if the problem came from there, but nothing has changed. My theme is Pinboard.
I don’t know what else to do. OVH just tells me to rewrite everything! Should I update wordpress ? Delete the database and create a new one? Something else?
Thank you very much in advance for your help
