I can't edit CSS

Last night i noticed that i can't edit my style sheet.I cleared my cache and deleted cookies , but is still not working.What can be the problem?  

Hello PixX,

What exactly happens when you try to type in the sheet ? We've had other people with this issue, I do not recall if it was ever solved though.

When i try to type in the sheet , well , is not happening anything..I can't select a row , i can't select a word , nothing..
  I don't know what to explain much more..

Does this occur on one browser or multiple browsers ?

I have the problem only on Google Chrome , i see on Mozilla is working fine.

I see, so it is another Chrome problem.

I will try and see if there is a solution or if someone else would know.

Alright. I will wait your response.

I have the same problem. Hopefully Chrome will fix it soon. I'm glad to learn that it works on other browsers.

Hello,

Do you have an ad blocker on your Google Chrome? Try disabling it.

Yeah , i'm using AdBlocker extension , i disabled it on my forum and now i can edit it! Thank you Jophy , this topic is solved.
