I have a problem, a file from wp-admin has been modified alone or after deactivated/activated my own plugin . I never modified any files inside wp-admin, I don't know why now. I am currently creating a plugin to add some information inside database from a form . After updating a table inside database, i must deactivated and activated the plugin to apply the changes. Also I have to get a backup of one file inside wp-content from my host ! I can't imagine that this process was able to modify a file of wp-admin

Parse error: syntax error, unexpected end of file, expecting ')' in website/wp-admin/includes/schema.php on line 440

after checking, the content of the file is deleted after line 440: "'ping_sites' =>

Does anyone have any idea why.

    Most likely it was an automatic update that failed to complete. The solution to that is to perform a manual update: wordpress.org/support/article/updating-wordpress/#manual-update I doubt deactivating and reactivating the plugin had anything to do with it. Likely a coincidence.

  • I copied / pasted the original shema.php file and the issue was resolved. @Jacob Peattie, I would like it to be that, but i haven't done manual / automatic wordpress core updates for a week. Something has done this or my host probably has an error in a script while restoring a backup, but the wp-admin folder is not supposed to be affected. I worked on my plugin without problem before the error appeared while updating a table in my database. This I would like to know, can it become a vulnerability? Should I question my host? thanks

  • You could ask your host. I still recommend doing a manual update, you don’t know what other files might be affected.

  • thanks, I will do that. I suppose there are no others files affected. I don't have other errors .

  • Just because you don’t see any errors now doesn’t mean there aren’t issues. Please just do the update.
