Running RHEL7 and Zabbix 4.0.27, system upgraded to 4.0.28 two days ago. Today I noticed no graphs were loading on any page - screen pages or individual graph pages. Only a broken icon showing. HTTP error log showed an error 500:
[Wed Jan 27 14:09:55.933697 2021] [:error] [pid 1417] [client X.X.X.X:38378] PHP Parse error: syntax error, unexpected ':', expecting ';' or '{' in /usr/share/zabbix/include/classes/graphdraw/CLineGraphDraw.php on line 1305, referer: https://X.X.X.X/host_screen.php?hostid=10496&screenid=4
After looking at the code it seemed like the ": array" part was unliked by php, and removing that allows the graphs to redraw. I don't know enough php to know if that's the right way to fix it, but I can see graphs again
