I've spent a few hours reading different posts on how to resolve 'Too Many Redirects' error. I've read so many different opinions on why it occurs - some say site was definitely hacked, some say permalinks problem, .htaccess issue, or possibly conflict of plugins. I don't know where to start to try to fix this.
One thing I've found is that when the site goes down due to too many redirects and I can't login into wp-login, is if I change the plugin folder name via FTP, I can then login to the site and it works (without plugins working of course). I don't know if that means it is definitely an issue with one of my plugins. I thought I could just rename each plugin and then try and activate each one by one to see if there was one that was causing the problem. However the site seems to crash as soon as I rename the plugin folder back to the original 'Plugins' folder name.
Any help or advice on how to figure out what's causing this would be much appreciated! I'm going crazy :)
