Hi
We are using Plantuml v6.24 with confluence v6.10.0, we are seeing issues with confluence pages that use the plantuml plugin in which they do not load but pages that do not have the plantuml in use load fine. When we look at the logs for confluence and we can see the plantuml flagged in same see below. We operate our confluence on a Linux platform.
Output of catalina.out below
Does plantuml have a log file when it is used with confluence and if so what is it called and where does it usually reside on a redhat linux platform?
