I had the Replace_Text extension working fine until the upgrade to 1.18.
I reinstalled the latest version of the extension (version 0.9.1), and it's showing up
but the page:
(and thanks again to PathosChild for the css help)
Missing how? Does it say "no such special page"? Or "only users in this
group can perform this action: administrators"? Or do you see a blank white
page with no text or user interface at all? (check your error log / error
reporting settings in php.ini)
Also, try 0.9.2 (the now-latest version)?
