AJAX webmail "CSSStyleSheet" error when switching tabs

Postby Xardas999 » Tue Jun 04, 2019 4:52 pm

Hello, colleagues!

Since some time I keep receiving the error in the Webmail " Failed to execute 'removeRule' on 'CSSStyleSheet': The index provided (9) is larger than the maximum index (8)." when I switch tabs, for example, from "Compose" to "Mail". It needs to refresh the browser to get access to the webmail. Also the mailboxes, folders in the Mail tab fail to open when I click - it needs to refresh the browser few times for them to get available again.

Zimbra 8.8.12_GA_3794 (build 20190329045002)
CentOS 7


all patched/updated. Looked for tmcat exploits - seems clean. Any ideas?
certificates are self-signed/ expired

------ UPDATE ---------
updating Chrome + resetting Chrome's settings to their defaults + Advanced Cleaning ALL site information was the solution. The issue has been closed.

-----------------------

The extended error report:
