There is something wrong with the output of the plugin in your site. The correct output is
<ul><li><span><span><a><img>, however in your site you get <ul><li><span><span><a><a><img>. You get an a element twice.

Could you PM me the plugin file jw_sigpro.php to take a look whether the problem is located there?

ok  ;)

any solution to my problem??

anybody?? :'(

Hi, I have the exact same problem and would really appreciate a fix.

I changed the filenames into simple standard characters and problem dissapeared... Found this and it helped: forum.joomlaworks.net/index.php?topic=9787.msg35312#msg35312
Make sure you clear the cache before you test.
