Support » Plugin: All-in-One Event Calendar » [Plugin: All-in-One Event Calendar] WP Dashboard is very slow in IE9 and Chrome (not FF!)

  • Resolved SPQC


    Pretty strange, I usually use Firefox for my browsing needs but I’m now building a new website with a fresh WP install and I recently added the All-in-One Event Calendar plugin.

    Haven’t noticed anything wrong until I try to log in as admin using IE9. That was very slow! i tried Chrome, same thing but a bit faster. No problem with Firefox.

    It not until I disabled All-in-One Event Calendar that speed was back to normal. Enabled it again and it was slow again.

    Are you aware of this?

  • weird, i just experienced the same thing, on safari/mac.
    the site is hosted locally on my mac whilst developing, and it has been working fine for a week. suddenly when i woke up this morning, admin pages took 30 secs to load until i disabled the cal plugin.
    upon reenabling it, it slows to a crawl again.
    so for now it’s disabled, but i really need this plugin.

    any pointers on what to look for? latest version of both wp and ai1ec

    I too had the same problem, in the backend of my site, I noticed it was very slow. but until yesterday did not give me no problem.
    I tried with firefox and chrome, but nothing, the problem persists.

    I just spent over an hour deactivating and re-activating plugins to figure out why my admin section was taking nearly 30 seconds or so to load the page and after I deactivated this plugin, it started to work well.

    The problem persists in all the browsers — including Firefox. I used the Firebug extension in FF and I believe it’s not working because the website is down and the page continues to load until it’s loaded but is eventually aborted.

    I hope this is fixed very soon because the plugin is used heavily on my website.


    Ok it’s also slow in Firefox after a CTRL-F5. 🙁

    What’s Is it really needed? Could go edit the sources to remove it until there’s a fix.

    Had the same problem. My (temporary) solution: in wp-content/plugins/all-in-one-event-calendar/app/controller/class-ai1ec-events-controller.php on line 120 remove or comment

    wp_enqueue_script( ‘’, ‘’, array( ‘jquery’ ), ‘1.2.5’ );

    Hope this helps for you too!

    Thanks robert, that helped for me. Don’t know what it removed of functionality, but at least i have my calendar back.
    Too bad one site down can hold back so many horses in 2012.

    edit: I know what went missing. all the little nice popup helpers on date and such. also, more importantly, it1s now impossible to set recurring events, as there’s no picker.

    Had similar problem with my theme, took similar action to fix the calendar
    and now it works

    My (temporary) solution:
    create folder /js/ in the wp-content/plugins/all-in-one-event-calendar/add/

    download the jquery-tools-1.2.5.min.js file from here

    place the file in the newly created /js/ folder

    in wp-content/plugins/all-in-one-event-calendar/app/controller/class-ai1ec-events-controller.php on line 121

    wp_enqueue_script( ‘’, ‘’, array( ‘jquery’ ), ‘1.2.5’ );

    change to these
    wp_enqueue_script( ‘’, ‘/js/jquery-tools-1.2.5.min.js’, array( ‘jquery’ ), ‘1.2.5’ );

    I think the site is back, no more slowdown and haven’t modified a thing…

    But having the file local is a good idead and could prevent future downtime of

    Hi all,

    JqueryTools uses a CDN to allow for hosting of their JS library, but its had some issues recently. Similar to the tip here, please see:

    We will be changing in a release tomorrow to not use the CDN anymore


    Im using this plugin on my multiple works and very happy. But now I have to share my problem with you : )

    Latest WP + Latest All in One Calendar
    Tested as All plugin disabled, other wordpress themes, no permalink
    now rewrite is false
    php memory 64m
    no jquery conflict

    i ve been reading all support items one by one for troubleshooting for one week.
    Everything works fine on chrome but Firefox and Safari gives No results found.
    any hint or clue would be perfect.
    Thanks to everybody from now.

    i ntoiced something it s not about browser type.
    logged şn user can see the event detail, visitors are not allowed to do that.
    probably i should edit class-ai1ec-calendar-helper.php
    around line 980
    or is event detail page user control somewhere else?
    thanks again.

    Are you sure you don’t have any permalinks? That url does not look right.

    Hi sauril,
    i guess i have this issue:

    – when user logged in event detail looks fine
    – when post date is not a future (post status = published) again event detail page works fine

    but visitors (not logged in) can not view post (if it s a future post)
    do you have any idea where can i change that query?
    problem almost solved any help would be great : )



    Hi umutsun,

    Sorry for not replying sooner. Can you tell me if this is also occurring in ai1ec premium version 1.8.3?
