One site of Multisite install has a redirect loop

Did you check your hosting control panel for redirects that could cause this?
Otherwise, it could be caused by a plugin, but I guess this should be one used on this error blog only.

@axel13, thanks for the suggestion, but I did check for redirects on the host already…
Any other ideas?

Yea… if you can’t find the problem, ask the hosting company for help. This has always worked for me so far. ??

So what’s the last few things you did to the site and the network?

new plugins or themes? Upgrades?

1. I did a backup with BackWPUp where I selected check and optimize database tables. BackWPUp reported some warnings, including some for this site.
2. I uninstalled Bullet Proof Security, and tried to install Better WP Security. It hung on backing up the database, so I uninstalled it and re-installed Bullet Proof.

@axel13, thanks for the suggestion. I submitted a support ticket.

Did you delete the plugin folder for Better WP Security?

Also you may want to run a repair on your DB. If it hung, you may have a crashed table.

@ipstenu, thank you for your suggestions. Just deleted the Better WP folder, and ran repair on DB – no problems found.
Still This webpage has a redirect loop…?

Anything else you suggest?

Thanks…

Subdomains or Subfolders?

If subfolders, you don’t happen to have a page in your main site with the same name as the subsite?

subdomains…
no pages in the main site with the same name…

Check your error log. Anything come up when you hit that site?

@ipstenu thanks for your suggestion, but nothing comes up in the error log…
