#47925 (In Topic #10483)

(or sometimes blank screens)

A PHP file is corrupt.

Note that blank screens may also be caused by the memory limit being exceeded.

How did this happen?

The file was probably uploaded incorrectly when installing/upgrading.

How do I fix it?

You can use the 'Integrity checker' option within the upgrader to find a list of all corrupt files. You can access the upgrader by calling up the '/upgrader.php' URL on your site.
Alternatively append &keep_show_parse_errors=1 to the URL (or ?keep_show_parse_errors=1 if the URL you are adding to it doesn't have any parameters on yet). This will allow you to identify the offending PHP file.

Once you have identified which files are corrupt you need to re-upload them. Download the manual installer from the ocPortal website that corresponds to your version, and then upload the files using an FTP client (or by some other means if you prefer).

Was I helpful?
  • If not, please let us know how we can do better (please try and propose any bigger ideas in such a way that they are fundable and scalable).
  • If so, please let others know about Composr whenever you see the opportunity or support me on Patreon.
  • If my reply is too Vulcan or expressed too much in business-strategy terms, and not particularly personal, I apologise. As a company & project maintainer, time is very limited to me, so usually when I write a reply I try and make it generic advice to all readers. I'm also naturally a joined-up thinker, so I always express my thoughts in combined business and technical terms. I recognise not everyone likes that, don't let my Vulcan-thinking stop you enjoying Composr on fun personal projects.
  • If my response can inspire a community tutorial, that's a great way of giving back to the project as a user.
