Greetings
Forum owned and always I receive an e-mail and repeated this message is always what is wrong and how I would like to correct error in the forum

Access denied for user'**********'@' localhost '(using password: YES)
/ home / alruxasd / public_html / vb / includes / class_core.php on line 314
Version 4.1.0

I have a forum and another message appears to browsing and does not appear subject rather than the error message appears, what is the solution ...

Fatal error: Allowed memory size of 16777216 bytes exhausted (tried to allocate 122880 bytes) in / home / islamicf / public_html / vb / includes / class_core.php (4078): eval () 'd code on line 103

First error means the mysql user is being denied access to the database for some reason.

The second error is from a modification. But the basic problem is a server issue. You need to contact your hosting provider and request them to increase the value for your mysql setting: max_allowed_packet

You can see more about the error in the manual here - http://www.vbulletin.com/docs/html/troubleshoot_mysql_errors
