I downloaded and installed V 4.0.0 and navigated to the plugin page and couldnt find rest api on the list. Done a manual import and still no success. I decided to downgrade to 3.9.3 (last working one that i used) and the plugin was there. installed the rest api plugin again and navigated to the server > server settings to Rest API. i click on it and i get a blank page.
@Redeyes this is strange. the full list of plugins dont load on my openfire installed. 5 in total. and rest api happens to be the most important plugin i need lol. as soon as i click on it it seems to load and then a blank page. the same as REST API Installation Problem however ive installed openfire on my ubuntu server.
The problem with the blank page was the incompatibility of the plugin to openfire version < 3.10. It’s seems to be that the old plugin 1.1.7 is not anymore available.
I would recommend you to use the openfire 4.0. I think something was wrong by the update to 4.0. Try completely new installation of 4.0.
