This plugin allows you to dynamically (i.e. at the time when a page is generated) replace code and text from themes and other plugins with code and text of your choosing before a page is delivered to a user’s browser.
Because the find and replace happens in real-time no changes are needed to plugins or themes which means upgrades remain easy!

Real-Time Find and Replace


Works realtime and can parse regex



Handy note:use / or ~ start AND end, use \1 \2 etc to replace with the ( ) groups


Works as advertised

Set up find and replace rules that are executed AFTER a page is generated by WordPress, but BEFORE it is sent to a user's browser.
