I can't post new posts on my forum. how do i solve this problem?
@onurkansan you were told by @robert to fix your forum base URL, but you didn't.
This:
https://biansiklopedi.com/community/
has base url /community/
and this (for example):
https://biansiklopedi.com/Forum/kitap/kelebek-ozeti-henri-charriere/
has base url /Forum/
This is not gonna be resolved by itself, you will have to fix it (and do not use Capital 1st letters in urls).
More on this to help you out. Do the following to keep your indexed topics in search engines:
1. Change the "/Forum/" to "/forum/"
2. Find the "/community/" and change it to "/forum/"
Please register a simple user and leave user/password here so we could login and check the issue.
BTW, it would be better if you disable the right sidebar for the forum page. Just edit the forum page and search for an option to change page template to something like "No Sidebar" or "Full width" to remove the right empty space..
