From the T103 thread:
Take_103 JHFA is now GA. Do not install Take_91.

Over the past week Chrome has stopped working on R77.30 and R80.10. Just built a test R80.10 with JHF91 everything works except WEBUI with Chrome (IE works) however no browser will import any hotfixes to R80.10 base install or JHF91 or a new T5 install of R77.30. Chrome on Server 2003 which is not updated does work.
Checkpoints original solution to this was:
wow! the balls!
This is not a Check Point issue, but an issue with the browser.
As a workaround, use Internet Explorer, or contact Check Point Support to get a procedure that will work around this issue. A Support Engineer will make sure the procedure is compatible with your environment before running it.
This has been updated and now a workaround has been provided publically:
Gaia Portal shows blank page after log in with Firefox 5x or Chrome 66
As a workaround, use Internet Explorer, or run the following command from Expert mode on the affected machine and then reload the Gaia Portal login page:
[Expert@HostName:0]# grep -q "form.el.dom.action" /web/htdocs2/login/login.js; if [ $? -eq 0 ]; then echo File is already modified, exiting.; else echo File backed up and modified. ; sed -i.bak '/form.isValid/s/$/\nform.el.dom.action=formAction;\n/' /web/htdocs2/login/login.js ; fi
Apparently fixes the issue.
