Support » Plugin: Events Manager » PHP warnings after updating to v. 5.5 [fix]

  • Resolved Mickey Kay


    Hi there,

    Just wanted to let you know that upgrading to Events Manager 5.5 resulted in a bunch of PHP warnings getting spit out, like so:
    Warning: preg_match() [function.preg-match]: Compilation failed: nothing to repeat at offset 1 in /home/mmadminrdr/ on line 205

    About, a dozen altogether. Anyhow, it took awhile, but I finally found a thread that suggested this fix, which worked for me:
    Just resave the permalink settings in Events > Settings > Pages > Permalink Slugs

    Thanks, what thread are you referring to?

    I’ve never come accross that warning before…

    Hi Marcus,

    Here’s the thread I’m referring to:

    Just to help in case you’d like to troubleshoot, here was our setup when the issue occured:

    • WordPress 3.6
    • Genesis 2.0
    • Events Manager (updating to 5.5)
    • Events Manager Pro 2.3.7

    The warnings appeared immediately after updating from our old Events Manager (regular, not pro) plugin to your latest release (5.5). I repeatedly disabled all other plugins but to no avail. I also tried disabling the plugin and resetting permalinks (the errors disappear when permalinks are set to default, however we need to use permalinks) but whenever I reactived Events Manager the warnings reappeared.

    The only thing I could get to work was what I mentioned above about resaving permalinks in Events Manager, which leads me to believe there’s some issue occurring on update. Just wanted to give ya’ll, the developers, a heads up.

    thanks for the info

    are you using permalinks?
    also, do you have an events page selected?

    oh, and what version did you upgrade from 🙂

    Hi Marcus, I have a similar problem
    I use WordPress 3.6. with Events Manager 5.5.1 nonpro
    if I change the permalink in WordPress from standard to another option, I receive lots of errors like this even if I deactivate all other plugins:

    Warning: preg_match() [function.preg-match]: Unknown modifier '/' in /home/.sites/97/site1595/web/servus/wp-includes/class-wp.php on line 204

    Without ‘Events Manager’ the permalinks are working fine.
    Every time I try to change the permalink-structure I got the same error.

    any ideas?

    Tried various ways and I can’t reproduce this. If one of you could give me access to your site so I can see your settings page, that’d be helpful, maybe we can reproduce this.

    You can submit info via our contact form and reference this thread so we know it’s you.

    The only wierd thing i see between both errors is that they’re showing different lines… maybe worth pasting that specific line in question.

    Thank you for your reply Marcus,

    I’ve installed WordPress from the ground in another folder as an exact copy of the one with the troubles but I couldn’t reproduce the error again, maybe because I’ve changed the permalinks before I installed the Event Manager plugin.

    I think it’s easier to delete the buggy website and go further with the new clean one.

    I`ve learned to not fiddle around with permalinks at a finished website.
    Now the headache is gone and your great plugin works very well!

    with kind regards
