Warning: ini_set() has been disabled for security reasons in ... on line 185

I have disabled iniset on my server. I can still create vbseo sitemaps. Should i ignore this eror or remove disabled fucntion from the server?

what do you recommend?

ini_set attempts to over-ride any set server settings so something can compute correctly. If its running fine, you shouldn't have any issues as your server has enough 'core' resources available already. It's probably a mod_security or suhosin thing

Ok understood thank you.

I heard ini_set can cause both security and performance problems. For this reason i recommend at future sitemap generator completly remove the iniset function within the codes.

It is needed to over-ride some servers low settings, especially shared hosts, so it doesn't time-out. There is nothing intrusive about trying to inscrease the max execution time, etc of the script with reasonable parameters.
