Yes, the problem is here from the “Cache” module and a problem of the twitter connection. As default the module enabled the cache feature which data is stored in the cache after got from the twiiter service. When you changed the position of the module from the right position to the left position => the joomla automatic create a new cache data using for the right position and may be the NET is slowly or something else, the module could not get the data from the twitter service. => thus, the module display blank content at the right position. When you moved back the module to the “left” position ( no more parameters changed ), the data is the cache data.
now, you open the file: modulesmod_jatwitterjatwitter.php
[PHP]
curl_setopt( $handle, CURLOPT_TIMEOUT, 40 );
[/PHP]
you replace:
[PHP]
curl_setopt( $handle, CURLOPT_TIMEOUT, 60 );
[/PHP]
with this change uses for increase time conntecting with the twitter service. you can disable the cache via the Enable The Cache parameter
