We are currently using Sugar ENT version 220.127.116.11 and have observed that on list view of Knowledge base module if we add filter on body field and search we get a white screen with the following message:
HTTP: 500 Internal Server Error
No enabled connection
Steps to reproduce:
1. Navigate to Knowledge base module and click Create Article.
2. Add an article with some text in the body field.
3. On the list view click create filter and select body field. Select body containing these word 'sample test'.
Blank screen appears with "HTTP: 500 Internal Server Error No enabled connection" text.
Tried the same on fresh version 18.104.22.168 and got the same error.
