Hello,
I was so excited yesterday to install fresh release of Apex 19.1, but after the installation it shows Internal server error in apex builder:

I can also see this record in httpd/error_log:
[Sat Mar 30 09:42:26.964546 2019] [http:error] [pid 9058] [client 192.168.152.1:49560] AH02429: Response header name 'Pragma Cache-Control' contains invalid characters, aborting request, referer: http://centos/apex/f?p=4000:4500:16530021057671::NO:1,4150:FB_FLOW_ID,FB_FLOW_PAGE_ID,F4000_P1_FLOW,F4000_P4150_GOTO_PAGE,F4000_P1_PAGE:100,4,100,4,4
These are the Pragma lines from page source. Seems like everything is fine here.
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta http-equiv="Pragma" content="no-cache" /><meta http-equiv="Expires" content="-1" /><meta http-equiv="Cache-Control" content="no-cache" />
Does anyone knows what exactly is wrong here and how to fix this?
Thanks for your suggestions,
Robert
