Hello everyone,
with updating our confluence to 7.13.7 and using a postgres db, we weren't able to install certain plugins with upm (webinterface). There should be more informations in the logs, but I wasn't able to find something in the logs.
Installing the plugin was possible when I copied the .jar directly into the install dir of confluence.

Is there a way to get more informations into the logs or something else to solve this problem?
