Running Joomla 1.7.3 on Linux.
After watching a video on what's new in Joomla 1.7 yesterday, I decided to use the Redirect component to set a link for a PDF on our site. (Still haven't accomplished that.)
I opened the component and found a bunch of old links, useless links and began deleting them, pages of them. Then I noticed that they were all JEvents links. That's odd because I'm not using JEvents on this site! The 1.5 version did use JEvents. (I used SPUpgrade to convert.) However, I didn't install JEvents on the new 1.7 site. (We switched to a registration component instead.)
I continued deleting, but it was going very slowly. I decided to switch the number of links listed to "all" so I could just get it done. That produced an error message. (Sorry I don't recall the exact message; it was a white page with just a couple lines of text and there was something about too much data or lack of memory/resources.) With the component now set to show "all" redirect links, it could not show the admin redirect component because the volume was more than the system could handle. I could go to other parts of the admin, but redirect component always resulted in an error.
Using PHPAdmin, I was able to delete the links a couple thousand at a time - all 95,000+ of them!
So now I'm able to get back into the Redirect component and have reset it to only show 100 links at a time.
I double-checked (admin console + FTP files) to make sure that JEvents is not installed. It is not. (Full disclosure: I had the old 1.5 site residing in a folder in the root folder. It does have JEvents in it, but Joomla 1.7 shouldn't be accessing that, right? The folder was named "15", but I've renamed it to "15-old" to prevent any confusion with IDs on the 1.7 site. I've since moved it out of the public_html folder.)
Global cache is OFF. Turned the redirect plugin off.
Wanting to find where the problem was, I turned the Redirect plugin on again, viewed the site, checked the component again and found ... over 100 links! All of them are for JEvents.
Here are a few samples:
(I'd rather not list the domain in case this is a security issue.)
The last one is especially confusing because when I look at folders via FTP, there is no 'jevents' folder under 'components' in the root folder. ('com_jevents' is not in the root/components folder, either.)
There is no "New URL" or "Referring Page" for any of the current links. The status is "Unpublished." However, when I was deleting from the database, I noticed a few statuses of "-2" and saw one new URL that has nothing to do with our site, certainly not anything I put in there. (Security issue, perhaps?)
Cleared the 100+ links. Cleared browser cache. (Global cache for the site if off.) Did a few page views in the front end, and now there are dozens of new redirect URLs again.
Is this a bug, possibly a security bug (since one redirect link was set to another site)?
Any ideas why these links keep appearing in the redirect list ... where they are coming from?
