Gota This Error?? How to solved it
The maximum server load limit has been reached. Please check back later once the server is less busy.

Clearly, your server is overloaded.
ACP > Configuration > Server and Optimization Options > *NIX Load Limiting > 0
Put "Server load = 5" then disable "Gzip compression" in Performance options
