hi,
I believe you need to switch off APC in your php.ini.
Can you paste your environment info from the C5 dashboard?

your php memory limit needs to be 128M.
Was this installation done by an installer that skips the various jnstallation checks?

Yes it was installed on a GoDaddy server by a program called Installatron. Was a one-click install with no questions asked.

I have no experience with them as a host but if you search for godaddy you'll find multiple threads where people have tried them and given up as a bad job.

But, your main issue is that PHP does not have enough memory to run Concrete 5.7 properly.
You need to up your php memory limit to 128M or get godaddy to do this for you.

If this is not possible then I can't imagine that it will ever run properly on that hosting.

Thank you for your help Andy. GoDaddy have increased the memory limit which initially seemed to have had solved the problem, but unfortunately I still get the error messages same as before. Is there anything else which could be causing this error? It makes the running of the site look very unprofessional for the client.

hello,
you need to get godaddy to set the apc flag to 0 / disable apc in the php.ini.
That shoukd stop those errors.

Yep that did it. Thanks again for your help.

Hi.

I have the same problem but have ignored it until now. Does Go Daddy have to change the php memory or can I? How would I do that?

What is the path to the php.ini file?

Thanks
