How do I get assurances that my CMS is not corrupted? Is there any way to test my CMS is fine? I read various comments on checksum errors after upgrading. I noticed it was easy for some people to manually overwrite the files that had checksum errors. I don't feel comfortable going to other sites like Gethub for my situation because it looked more 'integrated' with the core. My checksum error: The checksum is not equal: install/classes/ia.patch.applier.php (seems modified). Skipped Warning: rmdir(/home/projec10/public_html/home/cms/subrion/tmp/cache): Directory not empty in /home/projec10/public_html/home/cms/subrion/install/classes/ia.helper.php on line 111 Should I be worried?
