Breaks the wiki if $wgELuserRight is used. Then although it's listed at Special:Version Special:ExternalLinks doesn't work. Also there is no Validate external URLs in sidebar.
Topic on Extension talk:ExternalLinks/Flow
Please check 1.1.3
Working nicely again. Special:ExternalLinks also, although a link from Special:Version is missing. Many thanks. It's a very handy extension.
Cannot fix since I can't even log in to MW 1.27.1.
Just installed 1.1.3 with MW 1.27.1 - added $wgELvalidationMode = 'cURL'; to LocalSettings.php. Links are detected correctly but not validated. Anything else required to enable validation?
Very strange: reinstalling in a clean MW 1.28, I see ExternalLinks in Versions but not listed on Special Pages. In the PHP error log I see this: PHP Warning: Parameter 1 to efExternalLinksToolbox() expected to be a reference, value given in /Applications/MAMP/htdocs/wiki/includes/Hooks.php on line 195
