Cannot edit index.php

So sorry for the empty post! I am having a chronic problem — I cannot get changes made to index.php. I ftp it, change it, ftp it back, and nothing changes. I went into the ‘templates’ section of the wp-admin interface and as always, am told I cannot save changes to index.php because I haven’t set CHMOD to 666 (it has always been set to 666, but wp-admin doesn’t recognize this). In addition, the index.php file I view via wp-admin is very old, with no edits since the original installation.
So far my only option has been to flush & drop all databases, delete all WP files and start again. Does anyone know of an easier way? Or had a similar problem?

Thanks in advance.

…details please…

Sorry, you put up the details 16 seconds before I posted that. Try deleting your index.php (on the server) before uploading your new one. And set its permissions at 755.

If you are ftp ing it makes no difference that the admin section says chmod 666 and all that malarkey. IMHO its borked.

I agree, completely borked. macmanx, thanks, I tried it but no go. One of the oddest things about all this is that it began because I wanted to change my css. I took ‘extreme’ measures and deleted the entire images folder. And yet the site looks fine. Where in the world is it pulling pictures from??? It’s like the thing saved itself somewhere secret and has acquired a life of its own.

Have you tried dumping your browser cache at all? Or deleting all files if you’re using IE?
