Hello specializedheli,

Thank you for your message.

It seems that mod_security is used on your server and its rules block some CS-Cart request when the store is being upgraded. I suggest that you should configure it according to the following recommended requirements:


If these recommendations do not help you, the problem requires examination on your server. Please contact us via Customer Help Desk and provide temporary access to your server by clicking on the Add record link on the Access information page of your Help Desk account so that we could examine the issue.

Thank you.

Hello - I have the exact same problem, but with this querystring in my URL…


and I receive the default 404 message. Do you think the same mod_security issue is happening? Btw this is a 2.2.4-2.2.5 upgrade.


I was able to resolve this issue.

I have HostGator shared hosting services. ModSecurity was responsible for the error. I contacted my host and had them whitelist the rule ID 390588. This worked and I was able to quickly and successfully upgrade from 2.2.4 > 2.2.5 > 3.0.4
