"Access Denied" when

  • I have suddenly started getting “Access Denied” while admin’ing my site. Note: I am currently in dev, and *have* been making changes.

    The “Access Denied” or whites screens happen with different types of functionality, utilizing the database.

    I can’t: Configure a User List, Create a New List, Run DB queries, so on.
    I CAN:: Use and search all UserTables and custom scripts pulling from the User and Meta tables. – I can see that the cache is Updating. It’s taking 2-3 seconds, and using every bit of RAM allocated.

    I did make some changes to core pages, (had too0, to remove blanks and record counts from filters options.

    I am at a loss. All of my other plugins are fine. But the site does seem more sluggish overall. Does anybody have any ideas before I contact our host?

    What I’ve tried: Checked User and File Permissions, Looked at SQL Processes and Locks, Looked for any updates or other activity. – Nothing ??

    Could be any number of things:
    maybe you broke something with code fixes,
    maybe it’s running out of memory (plugin is a bit heavy on the db the way it works at moment with csv cacheing ) – if you have lots of users and lots of meta data that could be cause some probs.

    Try googling and see if any of the posts might relate to what you did

    Note best way to remove ‘blanks’ in the filter is not to have any blanks in the data (wink) – it doesn’t show if there aren’t any. ie make sure each user has a default value for the field you are filtering. You can test that quickly by ticking ‘exclude blanks’, rebuilding cache.

    It’s never ever a good idea to edit core code – you may need the updates! Better to look for other ways. eg: amr_show_filters is ‘pluggable’ – you can write your own function in separate site specfic plugin and thus still be able to update the base plugin.

    Suggest you backup the changed plugin. Revert to the unedited. Check the memory, check for any database issues (any ‘repairs’ flagged – maybe the db got corrupted)

    Once you have it stabilised again – either figure out a better way to achieve what you want, OR do a code compare (eg: in notepad++ on your local test system – you do have one right?) and see what changes you made – maybe you’ll see where it went wrong, maybe you can gradually add the changes back.

    Ok. Thank you for this I have pretty much done all of this at this point, aside from scrubbing the data, which has come from other sources, and likely will again.

    Can I assume that it’s easy to disable the creation of CSV caching if you know that you’ll never need it? – It would be based off of that checkbox in the configuration, right?

    Thanks again!

    1) csv caching is not what’s causing the problem – works elsewhere. White screens etc are usually code change bugs.

    2) as far as disabling: Yes and No
    Unticking the csv link checkone will disable the generation of a csv file for download. However they way the plugin works at moment, becuase it cam about to deal with some odd data in a generic fashion, it’s whole caching thing gathers up the data and stores it in a csv string in the DB.

    Please let me know how you go.
