Hi,

I have just upgraded from 4.5.1 to the latest build of V5. The upgrade process was ok.

I have successfully activated these plugins:

Font-resize,post-preview, Private Messaging, tiny MCE

Now I tried to activate the next one, subscriptions. After activation I get a white wp-admin screen (can be fixed by deleting the plugin again.

The error log says:

file: /www/problem-with-post-edit-buttontdocs/w005c921/FOTOCAMPUS-2012/wp-content/sp-resources/forum-plugins/subscriptions/sp-subscriptions-plugin.php

line: 162

function: sp_subscriptions_do_install

error: Duplicate column name 'topic_subs'

ALTER TABLE wp_sftopics ADD (topic_subs longtext)

I tried to activate other plugins (watches, admin-bar) and also got a white screen in WP-admin.

I assume it is a memory issue, as I did a test-install in another environment (same server though! / Hosting provider) and all went fine.

Could you give me a hint on what might cause the problem? Thanks

What happens if you activate the subscriptions plugin for a second time?

Actually the same. I meanwhile solved the issue. As I could nail  it down to the plugin I checked the memory resources available. With WP3.5 and the other plugins the 64 M Limit was exceeded. I changed wp-config and htaccess to allocate 256M for the site and now SP and also the other plugins don't cause a problem anymore.

The memory problem might also have caused my other problems concerning the language files.

Curious. I would have expected a memory error to show up but if that solves everything then great. Just WordPress without any plugins is currently starting to demand more than 64MB of php memory so it is not a surprise you ran out.
