* Hello,
* When I click on the Arrows to go from month to month I get the following error:
* Error: em_ajaxify is not defined
* The AJAX still loads each month but the error comes up each time you click the
arrow.
* Note: this is for the full calendar being displayed on in a template file (not
on the specified “Events” page).
* Does anyone know whats going on?
* Thanks in advance.

* Lets start with the browser.
Which browser are you using and which version?

* do any of the event calendars work? if not then it’s a js error, otherwise it
could be a bug (although no complaints like this yet)

* On MU installation we got the calendar to work AFTER we checked DB and found
that Blog ID was missing in em-events-table it was either NULL or 1 -> like the
main blog.
So my question was answered why the events are not accessed when
setting option to: Link sub-site events directly to sub-site? We will create
some events to see if this is now properly inserted into the db. ———————————————————————————————-
With ID in the correct Blog it works just fine see small calendar: [http://forum.portico-bangkok.com](http://forum.portico-bangkok.com)
On the main site we have problems ALL browsers throw this error jQuery.datepicker.
setDefaults(jQuery.datepicker.regional[EM.locale]); datepicker is undefined
* and
* jQuery(function($){$.datepicker.reg…nthAfterYear:false,yearSuffix:”};});
datepicker
is undefined So we are checking now all plugins and deregister scripts one by
one for this page to see what is causing it.

* hey dorothai, we’ll look at some of this today (along with your other issues).
Mind you, do you have WPLANG set to anything? that shouldn’t happen if empty
if you have a ticket open let me know on there

The WPLANG was simply empty. The datepicker works perfectly
now. I will let you know about the outcome of the tests with blog_id.

things a bit more efficiently 🙂

* None of the calendars seem to work (they all give the error). I haven’t modified
any of the js files as of yet. Is it possible it’s a plugin conflict?
* I’m not sure what to do to fix this issue, is there a different way to use AJAX
or worst case turn it off and still be able to page through the calendar?
* Thanks for your help.

* You can check if any other plugin is using
ajaxify by running a search with
dreamweaver throughtout the plugin directory and theme directory. Then you can
deregister the javascript from the other source for the events pages, where ever
you display the calendars. We have tested the calendars in IE7 – IE8 – IE9 –
Safari and FF they work on all browsers.

* Hmmm, even with all of my plugins turned off I am still getting the error.
* I am searching the plugin folders now.
* Is there any required settings for the plugin AJAX to work (within the plugin
settings or otherwise)?
* Note: I am using a modified version of the Twenty Ten theme.

* you should try the default twentyten theme, good chance it’s your mods if the
plugins aren’t causing an issue. unless you have moved your domains e.g. from
a local to public server, that can cause ajax issues in several plugins.

* Ok, so I updated to the newest version of events manager and now I get the same
error but now it doesn’t work (when I click the next button the overlay comes
up with the overlay and appears to be loading).
* I tried switching back to the default theme, but the same issue occurs.
* Any ideas?
* I’ve also tried adding and removing jquery around in the header, but no luck
with this.
* Here is my header code in a nutshell (not sure if it helps any):
* ```
Exhibits
```

* have you tried disabling other plugins also? if it’s a js error it’s 99% chance
that this is your issue.

* Hi Marcus
he could try to deregister the scripts of other plugins or theme on
this page, yet he cannot deregister the style of his theme.
* add_action( ‘wp_print_styles’, ‘my_deregister_javascript’, 100 );
if(is_page(‘
Thailand Events’)) { wp_deregister_script(‘premiumpress’); //this is the theme
we use wp_deregister_script(‘bp-album-js’); wp_deregister_script(‘more hooks
here’); //this has also a calendar and date section as it wp_deregister_script(‘
as many as you need’); } } also styles can cause it as css classes are building
the calendar and click functions is most often connected to a css class like
arrow
* add_action( ‘wp_print_styles’, ‘my_deregister_styles’, 100 );
function my_deregister_styles(){
if( is_home() or is_page(‘Thailand Events’) ){ //calendar on homepage and events
page wp_deregister_style( ‘bp-album-css’ ); } }
