@wpyogi Apologies – I was not aware of the convention.

If I may comment on your answer, I don’t see how adding “display:none” to text that the OP has already stated has been removed is going to address the issue.

I have a similar issue with changes to single.php not being updated in the site.

I have cleared my WordPress caching plugin (W3 Total Cache). I even disabled the plug-in.

Tried clearing browser cache. I even tried using a difference browser.

The only other thing I can think of is “advanced-cache.php” in “Drop-ins”. Could this be the issue? If so, how do you flush its cache?

Can confirm that changing line #441 to:

update_option( ‘wpseo’, $options );

instead of:

update_options( ‘wpseo’, $options ); (notice the “s”)

solves the problem.

+1 for sucuri.net.

After grappling with the problem myself for the best part of a day, I threw in the towel and signed-up for their $190/yr plan. They sorted the problem out on all my sites and now continuously monitor/scan every few hours for anything unusual.

If you’re running a commercial / mission critical site you might want to consider using them, if for nothing else than piece of mind.

(No affiliation, just a recommendation).

Same issue here (with WP sites).

Looking around I found a bunch of .php files. I think it’s these files which are re-filling the .htaccess files with all the redirection junk.

For me, the dodgy .php files were found in various subfolders within wp-content/uploads.

I’ve weeded out all the files, changed all user passwords, ftp passwords and db passwords. I’ve installed BulletPoint, though I don’t know how much that’ll help (before I found all the dodgy files my .htaccess file was still getting overwritten, even with BulletPoint active).

Before, my .htacesss files were being overwritten within 15-20 mins of me clearing out the garbage. Now, it’s been 2 hours and everything is still OK – touch wood.

HTH.

If you’d bothered to read my original post you would see that updating to 3.1 isn’t an option for me.

Actually I HAVE already done the “smart thing” – I’ve dumped WordPress SEO and gone back to AllInOne SEO.

It may not be as slick as WordPress SEO, but at least the updates don’t break old installs. In addition, the developer doesn’t use a public forum to insult his users.
