Post > Submit button issue

[Forum Admin]

Few ( but thankfully not all) users have reported an issue with the post submit button
When they clicked on Submit(a post) button , the screen went blank and nothing happens.
The blank page asking you to post reappears
If this happens to you , don't worry. There is some glitch in the system.
No need to start again & submit post again . It already went thru
You can go back and check active topics page and your post or reply should be there.

There is not much anyone can do because this does not happen to all users and also it does not happen all the time.
Sorry about that.
