I first had opencart 2.0.3.1 runnning with OpenBayPro on Windows Server 2008, and this was actually working fine. I couldnt get VQMod to work though, and ultimately decided to migrate to a cloudlinux server instead.
I now have vqmod working but openbaypro no longer works!!
I've got 256Mb memory limit defined in both php.ini files (root and /admin)
I've got the store installed in the root folder for information.
When I go into OpenBayPro>Ebay>Manage Items and click on the white ebay button on the far right to start posting a product to ebay, I get a series of 500 internal server errors one after the other; it appears to be related (on the surface) with the querying of the ebay API, as it's all those boxes which sit doing nothing / very little.
I paid £24 to get welfordmedia to provide upgrade support and they've confirmed that openbaypro is correctly installed, and asked for info from my hosting company.
My hosting company replied that the website is hitting a 1Gb limit when these errors occur - i get 6 or 7 of these errors cropping up in the error log.
"[Tue Aug 04 16:52:24.870960 2015] [:error] [pid 859925:tid 140647495366400] (12)Cannot allocate memory: [client 212.161.29.54:55828] couldn't create child process: /opt/suphp/sbin/suphp for /home/mywebsite/public_html/admin/index.php, referer: http://www.mywebsite.co.uk/admin/index. ... duct_id=72"
I've informed welford media of this (but they've gone home for the day), they've been very helpful to date but just wondering if anyone has any ideas?
Tearing my hair out now, I've gone to massive effort to migrate multiple sites to linux, just to compeletly break one of the most important features which was working fine before!
I've replaced the .htaccess and php.ini files i copied over from windows server, with ones generated by scriptaculous on another domain when installing opencart, just to be sure.
phpinfo returns memory limit as 256Mb, which should be plenty for this process I'm certain.
Any ideas/help / bottles of cheap alcohol for drowning of sorrows very welcome
