 * Hi there
    When I try to update any plugin or theme, or delete them I receive 
   the following message: Deletion failed: Internal Server Error When I try to update
   wordpress to the newest version I receive this:
 * Fatal error: Uncaught Error: Call to undefined method WP_Error::has_errors() 
   in /nhldata/269/191269/data/web/web01/htdocs/wp-admin/includes/file.php:1504 
   Stack trace: #0 /nhldata/269/191269/data/web/web01/htdocs/wp-admin/update-core.
   php(501): WP_Filesystem(true, ‘/nhldata/269/19…’, false) #1 /nhldata/269/191269/
   data/web/web01/htdocs/wp-admin/update-core.php(711): do_core_upgrade(false) #
   2 {main} thrown in /nhldata/269/191269/data/web/web01/htdocs/wp-admin/includes/
   file.php on line 1504
 * I tried to deactivate all plugins but that doesn’t help. My website runs normally
   but I just cannot install, update or delete plugins or update wordpress. I searched
   for a solution but couldn’t find anything related to that.
 * Thanks a lot for your help, very appreciated!

 * Please install the health check plugin and report back its findings: [https://wordpress.org/plugins/health-check/](https://wordpress.org/plugins/health-check/)
 * You may have to install this via FTP by downloading, unzipping, and uploading
   the resulting directory to wp-content/plugins

 * Hi Steven
 * Thanks for your answer. I red that many people had problems with the health check
   plugin… Not certain if I should install it.
 * Could the problem also appear because some plugins are not running on wordpress
   5?
    I have some that I downloaded directly on the developers website… Thanks

 * I would not have recommended it if there were problems.
 * >> I have some that I downloaded directly on the developers website… <<
 * good luck with that.
 * Now, please use the health check plugin and show the output from the debug tab.
