I recently was trying to post a maths problem but when I click on submit it tells me that you can post once in every 40minutes as such I didn't post anything at all before this in few months so why this is showing up? Is this a bug or something please help? (Same happened when I was asking this in meta too right now one, there also it says to wait for 40 minutes so what you all are seeing is the meta post which I typed 40min ago) and now I need to wait for 40 more min to post the math problem because I posted in meta so don't know why it counted it as one time.
The 40-minute-limit is actually IP-based. So if you share you IP with other users, that would be a possible explanation why you sometimes can't post a new question and have to wait.
Users with < 125 rep on the current site, 40 minutes since their last question anywhere on the network (This applies to the user's IP address, not their account. If the user shares that IP with other users, they can be limited by the other user asking a question anywhere on the network; similarly, if the same user posts a question from a different IP address, they may not be limited.)
