The two most likely causes are either a script conflict or – more rarely – something that either changes the url being called or requests data to be sent from the server – which can appropriate the data we are expecting.

To test the first theory just open a script concole window and try the update to see if anythign gets reported in the error tab…

Remember – this is an Ajax call.

First theory tested and no messages…

I’ve checked all errors: net, CSS, JS, Security and Registries.

How can I test the second?

first theory, that would be bad…its an ajax request so there must be a resopnse…  if not would need to figure out what is blocking the response… ajax needs the response from the request…

the simple fact that you have the error message says the ajax response is happening…  and some plugins or themes incorrectly tie into the response and mess with it causing the error…

with the console open, the request would be shown, but you would have to expand the line that gets output to see the actual response…

I’ve got the following message

“GET http://www.rutersdemallorca.com/wp-includes/js/jquery/jquery-1.10.2.min.map 404 (Not Found)”

thats a wordpress issue with 3.6…  and harmless… they forgot to remove an include of a file that was deleted… its been fixed in 3.6.1 and 3.7…

If you want to send us some temp wp admin credentials with full sp admin capabilities, we can take a look and see what we see…  if that works, please send to both yellow swordfish AND mr papa… be sure to link back to this topic too so we know what its about…

Private messages sent.

I’ll create a backup just in case

so yeah, another plugin dorking with ajax responses…  in this case its wp super cache

<!– WP Super Cache is installed but broken. The path to wp-cache-phase1.php in wp-content/advanced-cache.php must be fixed! –>

Its adding that output to our ajax request/response causing it to fail…

it appears you had super cache at one time but perhaps uninstalled it incorrectly…  if you are not using it, remove the advanced-cache.php file from the wp-content directory….

Thanks Mr Papa!!

File removed and forum upgraded

great news!  thanks for the update!

I’ve seen that after the update the lists of New/recently udapted topics and Select a forum has desapeared from the top of the forum.

What can I do to have this lists again?

I see two problems. The first is that the Thickbox plugin you are using is loading a second copy of the jQuery.js library. At least that is what it looks like. Two copies being loaded is not good and the second copy will not be the correct WP version which is a ‘special’ version used for WordPress and supposed to be used by plugin and theme authors.

The second problem might disappear if the above is fixed but if it doesn’t then you are getting a type error because of the use of the ‘$’ shortcut for jQuery code. Not sure but I suspect this is from the Event Calendar plugin.

Thanks!

Thickbox plugin deactivated

Sounds like all is well then. Good news.
