# Database connection problem when uploading image

 * Hello, yesterday I made this script that manipulates the $file in the filter.
   It seems to work fine because it achieves all its purpose, even loading the image
   in webp correctly.
 * But the problem is that in each uploaded file I receive the email “There is a
   connection problem with the database.”
 * Does anyone know what is wrong with this? Do not code anything other than this
   script to manipulate the files.
 * ////
    Sorry it’s fixed now, it seemed to be a grammar error when I typed else
   instead of elseif.
 * I can’t find a way to delete this question. If they inform me, I will do it since
   it is solved and it was not necessary to ask
 * Thank you so much
 *     ```

   won’t make any difference 🙂 Marking it as resolved is good enough. Ideally, 
   you’d add a reply explaining what happened. By adding a reply, your topic falls
   off of the “no replies” view that many members use to find those still needing
   help. But this reply serves that purpose, no further action is required.
