apache error_log is growing very fast

I just took a look at my apache error_log file.

It is horrible! I got tons of errors and it is growing very fast.

Code:

[client 62.169.110.249] PHP Notice:  Undefined variable:  FiKy8iZQy0j in /var/www/vhosts/evangelie.ru/httpdocs/forum/vbseo.php on line 755

Please advise.

Hello Игорь,

please update the error_reporting setting in your php.ini to avoid notices being added to the log:

Code:

error_reporting = E_ALL & ~E_NOTICE

Oleg, seems like this helps.

I'm just wondering, do those warnings have any impact on performance? Should VBSEO team do something with those "indexes" so PHP will be executed more smoothly without any warnings?

Thanks.

Great! It shouldn't have a performance impact as long as you have error_reporting setting as above (it's default value), but we are going to eliminate them as well.

Thank you.
