uninstall.php Requires PHP v5.3+

I noticed this review at WordPress.org.

Once activated it and after of the message about the old PHP version, I tried to remove, but after clicking "Remove" the screen goes blank. I've tried other browsers and nothing happens. :(

When I setup the uninstall.php file I forgot about this scenario. The uninstall.php file will get pulled in by WordPress even when/if the plugin is not running due to a lack of PHP v5.3+.

In short, if you install QC to try it out, but cannot use it because your server is lacking PHP v5.3+, deletion of the plugin will cause an error (e.g. blank screen) because the uninstall.php is being loaded, and it requires PHP v5.3+.

Possible Solution

• Move the existing code to an uninstall.inc.php file.
• Use uninstall.php as a stub that checks for PHP v5.3+.

A second look at this issue. The uninstall_on_deletion option in QC defaults to a 0 value (disabled). This means the problem I reported above should not occur, since one cannot change the option value when/if the plugin cannot be run to begin with. However, I still think a stub for the uninstaller is in order. Just to avoid the potential for this to occur.

ha! A third look. The uninstall_on_deletion flag, while still at a 0 value, would not prevent the uninstall.php file from being loaded. It only prevents the uninstall routines from running once loaded. So, again, best to include a stub for the uninstaller.

Interesting. Thanks for catching this and opening the issue. This seems like a pretty annoying bug. I'm adding it to the Future Release milestone to be worked on in the next development cycle.

@raamdev This has been resolved by the PRs I submitted earlier.

Next release changelog:

• Bug Fix: Fixed a bug with the uninstaller whereby attempting to uninstall after receiving a notice that PHP 5.3+ is required would result in a blank screen and require manual removal of the plugin. See #334.
