Forums Error Preventing Posting

In attempting to make a post on a thread in General Discussion instead of posting my reply I'm given this error.

"New forum post cannot be made due to either you have reached to your daily limit or your main character's level is not high enough."

My linked character is level 50, and the number of posts I made yesterday is greater than the number I've made today (I've only posted 8 times today versus the 13 I posted yesterday). Is the impending level cap increase having an adverse effect on posting rights on the forums?

Append: Square must have instated a post limit for the duration of the maintenance, I've been unable to post do to 'daily limit or level isn't high enough' all day after just 8 posts. Hope it is this and not the new level cap having an adverse affect.
