Only allowed few active plugins (17 posts)

    WordPress is only letting me have 27 active plugins at one time. If I activate more than 27 I am forced to delete the plugin files of an active one from the server.

    Plugins already on the server however (not new ones) can be activated/deactivated freely.

    When activating a new plugin, the entire admin console vanishes, leaving me a blank page.

    Hi Crhristopher,

    Is it always the same plugin that is causing this? I.e. did you try to enable a different plugin?

    As far as I know, WordPress does not impose such limits.

    Well, had a few issues, site moved server along with 2 others running WP. Those sites came back up, and raw HTML/PHP etc. files on Technology Bloggers did too, however WP was completely down, all pages visible and admin console.

    Reloaded wp-admin and wp-includes but no luck
    Started removing plugins, and after removing a few, got it to work again.

    Hello Dolly was disabled but still installed, I can enable and disable that at will.
    If I add a plugin back to the server via FTP (or via WP), it is fine, click enable and entire admin console goes down.
    If I add a plugin back to the server via FTP (or via WP), it is fine, disable an existing plugin, click enable and it is fine. I can then enable the existing plugin again.

    Weird hu? Why is it doing that?

    Do you understand, I think what I have written makes sense?

    just added AddThis plugin to the server and disabled Hello Dolly but admin console went down. Had to remove the plugin files from the server... back up now...

    This is really weird, any suggestions?

    Tried the plugin, it did install and activate, but didn't seem to work :-/

    Is there anywhere that a cache of plugins is installed? I seem to be able to install and activate new plugins, but not ones which have been on the blog before.

    Can I wipe the list, so I can install any plugin?

    Thanks
    Christopher

    Apparently WP was using all the resources on the shared server it was on, so has been moved to a probation server.

    The WordPress site has been taking up a lot of CPU which suggests that the scripts not are in good order.

    What can I do?

    Hi Christopher,

    WordPress does not keep a specific list of plugins which were previously installed. The only record there is of this, is if such plugins write to the database.

    Check the wp_options table. This is the place where plugins usually write data. Check if you find any data relevant to some plugin you had removed and remove it.

    make a backup first, always!

    I have been told that the 'maximum memory limit is 20MB on the shared platform' is this enough? I would think it is...

    No - you need at least 32M for WordPress 3.

    That is the limit they have said, I don't want to move, so what can I do?

    Use as few plugins as possible and stay away from any function-rich themes.

    Ahh... we have loads of plugins (and need them) and loads of users, uploading an updating all the time. Currently users can't get in, the site isn't coping, only admins can log in, and I can only get some pages :-/

    Any way of hosting/straddling one site across two domains - therefore have 40MB limit?

    Images and admin on one domain, static files on another?

    Hi Christopher,

    If you have a lot of users logging in and the site is generating more and more traffic, in this case it would be easier to simply switch to another hosting provider or dedicated server. Dedicated servers typically start at around $25 a month, so it is not a huge expense.

    What you are trying to do is kind of "patching" but it would be much better if you simply migrate to a better solution.

    The issue seems to be sorted for now, maximum memory available is now 64MB.

    Also, check with your host and get them to add the following:

    suhosin.post.max_vars = 5000
    suhosin.request.max_vars = 5000

    It's WP running out of memory. This can mean limited number of menu items, image resizing not working and number of plugins concurrently.
