I will check this out. First thought: it can be a security setting on your phone, the browser banning activities that it detects to be too old for its required security level. If you have an old android phone, try to repeat submitting a post with that. If it works, it can be the issue. But I will check it myself too, soon.

I am unable to post via android phone.
When i press send it goes to the blank thread.

You see I added this test member from Android, and it did post. I will try to figure out what the problem is on your side. What browser do you use?

This seems to be exactly what I suspected. You need to use another browser. Congovibes forum is based on a reliable but old engine, and some browsers block certain features. It is too big work to update the forum to the level your browser requires at the moment. So now all you can do is to use a different browser. I used the Google app on my phone, but you may try Firefox. Or Kiwi browser. I am planning to update the system of the forum in the future, but I don't have time for it now.

Have you tried?
