v2.0.3.1 is quite an old version. In order to avoid passed headaches that used to be reported a lot on the forum to rectify this issue, it would rather be suggested to upgrade to at least v2.3.0.2 release of OC.

You have an error in modified file, which means one of your extensions is causing the issue. The only way to solve this is to look into this file. Or you can simply try to set Display Errors to No in store settings.

Alert messages ignores the display errors messages. Following my instructions above will save you lots of headaches since the alert JS function does not take PHP errors into considerations as the reported issue has been fixed since quite sometime.
