a white page appears on admin plugin options page

Does a link to the options page appear in the admin menu (sidebar)? There should be a submenu-item “Admin Columns” under “Settings”.

I see the link on the sidebar. when I click on Settings, appears this URL:
https://avi-inmobiliaria.com/wp-admin/options-general.php?page=codepress-admin-columns and the page appears completely white… it means that this plugin doesn’t work or something happens!! I have disabled the other plugins and happens the same…

Are there any relevant warnings or fatal errors showing up in your error log?

No!!! just a white page… on my browser. SO, when I activate the plugin and click on Options, this link appears on the URL: https://avi-inmobiliaria.com/wp-admin/options-general.php?page=codepress-admin-columns

and something must appear on the content area… but doesn’t appear anything…

when I press the come back button I return to the plugin admin page.

why does it happen?

How to see the error log? I have activated the wp-debug to “true”, and no errors appears.

And the page is completely white? When you look at the source, is there nothing there? If that’s the case, please send us an email (https://www.codepresshq.com/support/).

Completely white… no code!!!!

thats very strange!

I have send you an email

How can I send you wp-admin codes to check it?

Same issue here. Completely empty screen (…/options-general.php?page=codepress-admin-columns).
It works fine with my local installation, but not online.

Response headers on request:

DID NOT WORK (online) https://tinypic.com/r/16bkeg1/8

The issue with @joutm turned out to be a memory issue (with too little memory available). This is not an unlikely cause in your case, either, as it is working on your local installation. Could you turn on error logging and see if this might be the issue? What is the memory limit on your remote installation (you can use phpinfo() to find out)?

We optimized Admin Columns to use very little memory. Try running P3 (Plugin Performance Profiler) to find out which plugin easts up the most memory and deactivate it.

You can also try to increase the allowed memory of the server. Try adding this example to your wp-config.php or functions.php

ini_set('memory_limit','128M');
