Prevent changes in URLs from breaking incoming links with WPML Sticky Links plugin, avoiding any 404 error, when incoming links go broke.
WPML Sticky Links plugin prevents changes in URLs from breaking incoming links.
Instead of storing the URL of that page (at the time the link was created), the plugin stores the page number. Then, when the page is displayed, WPML Sticky Links inserts the permlink of the page you’re linking to. Whenever the URL changes all pages linking to it update immediately and will link to the correct address.
Sticky links controls
The plugin will turn all links in post body to sticky. You can also turn links in widgets and strings to sticky. It will also report any existing broken links and help fix them.
The Sticky Links admin screen tells you home much content may include normal links. Afterwards it scans that content and converts all links to Sticky Links.
