404 Error After Upgrade

[aslater]

Hi

I am hoping someone can help as we upgraded our site from 1.9.2.1 to 1.9.2.2 to apply the security patches but the whole site now gives a 404 error page not found on the frontpage and admin.

I have searched on the forums to see if I wasn't the only one but as this is our first magento site not sure where the problem could be.

Thanks

Alan

What method did you use to upgrade magento?

I would suggest restoring your backup copy of you .htaccess file.  I have had similar issue when there is not a .htacess in the root and the rewrites will not work.

Check your file permissions.  This happened to me and I changed the following:

index.php to 644

downloader/index.php to 644 

downloader/ to 755
chron.php to 644

chron.sh to 744

Also delete maintenance.flag in your main magento directory if you haven't already.

Thank you Crane_cio & Travis_Mc for your help.

I followed a step by step upgrade via ssh which goes through no problem at all but everytime it breaks the site with all pages showing a 404 page not found error.

I also checked file & directory permissions and they are all ok as well.

There must be an easier way of upgrading, would not a simple overwrite of newer files via ftp work at all.

Thanks
