Issues with creating categories in ads module.

Hi using the trial version of boonex dolphin 7.1.3.  when i click on "add subcategory" or "category manager" in the ads module my screen turns faded white but that's it. i can't add subcategories or manage categories. it renders this mod useless because nobody can add ads either. I tried on other developer websites and it causes the same problems. i'm using chrome but i tried it wih firefox also i believe and has the same problem. 

can anyone confirm this bug and will it be fixed in the future if there is something to fix. 

Okay so i tried with windows explorer and with that browser it works. pretty weird though that chrome and firefox got issues with it. 

Can't reproduce on demo.boonex.com in Chrome browser.

 okay thank you must be something with my browser settings then. 

i found the problem it's because of the ad blocker extension, in chrome and firefox.  should have known it was that.
