It may be the issue due to following reasons
a) mysql connection timeout in server
Can be fixed by any of following methods
i) Just change the line in file "seopanel/libs/mysql/mysql.class.php" line 35
- Code: Select all
$this->connectionId = @mysql_pconnect($dbServer, $dbUser, $dbPassword, true);
to
- Code: Select all
$this->connectionId = @mysql_connect($dbServer, $dbUser, $dbPassword, true);
ii) Increase the Delay between each spider crawl(seconds): from
Admin Panel => System settings => System Settings
Change delay time to 50 to 60
iii) If you are using Seo Panel version 3.0.0 or more, Use multiple execution of cron.
Execute your cron 3-4 times in a day. We have added this feature in 3.0.0 version onwards. So that once executed keywords will not be checked second time.
b) PHP execution time
It can be fixed by contacting your web hosting provider or increase execution timeout through the .htaccess file
