So, this morning in that support chat, they opened a ticket for for a tech specialist to check out the error:
"Your server is unable to create a session necessary for AbanteCart functionality. Check logs for exact error details and contact your hosting support administrator to resolve this error." that shows up on top of the admin login page.
Their response:
"I was able to duplicate the issue with the admin page, I have corrected the permission, set proper session path and re-updated the php version at
https://www.ipage.com/controlpanel/cgiManagement/phpplus.html but the admin page is showing same error. It seems to be issue with script or coding. Please correct the script by contacting application vendor and fix the issue.
If you have any further questions, please update the Ticket or contact us via chat support
https://www.ipage.com/chat ."
So, I don't know if that is a common issue that can be ignored without worry or if there is knowledge as to what is going on. I'll make some more searches tonight.
Concern #2, Every time the site is used (it seems).. the error log appends the bold error listed above. I just worry that error log will get very large in a very short time. Manually clearing the log seems tedious, and maybe i won't need to do it more than once a year(i can't imagine the file being that large even with 10,000 logged errors).
Thanks for everyone's time and help in this, I decided not to delete, as there may be some information in here to help others in their Ipage abantecart 500 internal server error.
