Ok, Im trying to create a forum under specific category and then post new thread in it but I couldn't. I click on post a new thread and then when I start typing the title, that little loading thing at the right top corner in the page won't stop loading. I click on create thread button but it does nothing however when I create a new forum under another category other than the one I'm talking about here, things seem fine and no problem whatsoever. Also Something strange happening in the ACP, it gets missed up for unknown reason. I disabled all the add one and still that won't solve the issue. Here is screenshot concerning this matter.
