Okay, so I originally had upgraded the all in one seo pack, and was using wordpress 2.7.1, so the website stopped letting me login to the wp-admin via wordpress. So I renamed the file via FTP, and was able to login, then I reinstalled all in one seo pack 1.6.12.1 (which was the version I was using before I had upgraded and got problems).
I deleted the upgrade all in one pack seo version which wasn't working, and now this new one has a problem when I click "enable" (all my previous settings are there on the all in one pack seo plugin), so it won't let me click "enable" because it says:
Fatal error: Call to undefined function esc_attr() in /home/chpic/public_html/wp-content/plugins/all-in-one-seo-pack/aioseop.class.php on line 1387
So how can I fix this? I have over 3,000 posts that used seo pack, and I don't want to lose all the data, etc. for them (if they haven't been deleted already…). So is there a way to fix the new problem?
