Oh thank You. Basically i have max_user_connections Problem My host told me We can't increase User connections up to 10. Is there any Solution for that ??
The only solution would be to upgrade to a better package. Only very small forums will work well on shared hosting, if you start to get more users and more posts/threads, you will get limitations like this.
You were probably not looking for an answer like this, but unfortunately it's the only way to fix the issues.
