So for anyone who is having problems posting or writing anything on the forums, you need to go change your settings. (usually just effects Internet explorer)
1) Go to your USERCP (click your username at the top right, then click USERCP)
2) Click on "General Settings" on the far left.
3) Scroll down until you see "Message Editor Interface" and click on "Standard Editor". Then scroll down and click "Save".
This should fix any typing issues you have on the forum until a permanent fix is found. Thank you!
