Uploaded ClassiPress file successfully - but do not know how to install it
Hello,
After uploading my new ClassiPress file successfully - I wasn't sure what to do next - so I left the page I was on - and went looking for answers. And when I tried to return to the upload page - much to my dismay - I found this message:
Fatal error: Call to undefined function is_multisite() in /home/cellbuys/public_html/
wp-includes/
wp-db.php on line 505
Can anyone tell me how to fix this problem? I do hope so.
Sincere thanks in advance,
Royal Star
