Can't import/duplicate, only sometimes (Joomla)

Error
  • With a new slider the import and duplicate option works once, then it doesn't, but after a while it does again.
Solution

If you have full version Admin Tools extension, then it has a .htaccess Maker. Between the settings there is a Set default expiration time to 1 hour option, which does, that it saves down the redirection of something, that you clicked on. This is causing, that our clicking on import or duplicatecreate a slider with a new id, in this example it will be 10go to slider with the id 10, will be changed to clicking on import or duplicatego to slider with the id 10, so the middle steps are skipped, it won't create a new slider, and it will just redirect to your previously created slider. You should turn this option off, and it will be fine.
