I believe I have 2.91 installed, but can't confirm since I am unable to gain admin access. My last update was more more than a year ago due to the fact I was inactive on the site. I recently logged in several times without any problems. Now I keep getting the following fatal error:
Fatal error: Call to undefined function is_rtl() in /hermes/waloraweb002/b443/moo.reversediabetes2/wp-includes/general-template.php on line 2102
I tried changing the password, but that doesn't work. NEED HELP! Any suggestions are appreciated.
