First time using the mailing list, hope I'm doing this correctly.
Im using MediaWiki 1.25.3, PHP version is 5.4.45 (litespeed) and database is MariaDB 10.0.22-MariaDB.
After editing a page, the changes are saved. But needing to make another change I went to edit again only to find the last version of the page before the previous edit.
Just updated via patch to 1.25.2 and then to 1.25.3. Also ran update on composer installed extensions. Had just installed Cargo to try it out (which was why I was making edits right after edits). Uninstalled to see if that removed the problem, it did not. Also did not find any mention of the problem on Cargo discussion page or mailing list (nor would it seem like a problem caused by Cargo). Not sure if the problem existed before the updates as I only use this wiki as a test wiki for new extensions and templates. Main wiki (on another server) was updated the same way (without adding Cargo) and does not have a similar problem.
After opening the edit page, refreshing the page does bring in the latest version.
