Dear Stefan, 

There is a problem with editing an Elog page in "plain" format with the following "User Agent" :

"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/16.1 Safari/605.1.15"

It duplicates the newline symbols such that "1<CRLF>2" becomes "1<CRLF><CRLF>2". If edited again - "1<CRLF><CRLF><CRLF><CRLF>2".

I blame the new version of the Apple WebKit. 

It works fine with Chrome (user agent: "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/108.0.0.0 Safari/537.36"). But fails with Safari. 
 

Could you please have a look? 

Thank you in advance,

I am still struggling to get ELOG running behind a load balancer and hope to get some advice here. As already reported in https://elog.psi.ch/elogs/Forum/69542 I observed an infinite loop of redirects when prompted to log in and using a non-empty password file. Without a password, the service worked as expected. This was with version 3.1.3.

With the new version 3.1.4-3, I get another error: "Invalid Content-Length in header" when I click on "submit" of a new post. Viewing the logbooks works fine. The instance is currently live and running here: https://elog.test.km3net.de but I might change it anytime due to debugging etc.

This is a kind of difficult thing to debug (I spent the whole day and no progress). The only thing I've found was this post: https://techcommunity.microsoft.com/t5/iis-support-blog/invalid-content-length/ba-p/3038724 where it seems that some responses are not RFC conform and were rejected in the load-balancer.

The load balancer I use is HAProxy, the same as in my old setup where I got the infinite redirects, and I can't find any setting which would work. To my understanding, the most basic setup should work just fine. The SSL termination is on the load-balancer side so ELOG doesn't even have to know anything about it. The configuration is below. I am running a single instance, so there is not even replication with session keep-alive via cookies or anything fancy.

I also want to mention that I am runnin around 30 different services behind the load balancer and none of them are having any issues with the SSL termination or the load-balancing itself, that's why assume that something in ELOG is either non-conform or buggy.

Any thoughts? I'd really like to use the same infrastructure for the ELOG service as for every other service (automatic certificate renewal via letsencrypt, load-balancing, easy movement to other nodes, SSL termination etc.), to minimise the complexity of our Docker Swarm system.

Btw. I am running ELOG with -v but I don't see any error whatsoever in the logs:

I downloaded the last elog-3.1.5-1.tar.gz to install elog.

All *.cxx files are missing.

I wanted to change some CKeditor settings so tried modifying elog/scripts/ckeditor to no avail.

I wiped elog/scripts/ and dropped a fresh download of CKeditor4, with only the basic extensions. But when I open the elog it still shows the full toolbar, with elog default style and with all extensions operational.

If I leave elog/scripts empty, I get "CKeditor NOT detected" when starting elogd and the HTML option is empty and shows nothing, all as expected.

Does anyone understand this? Is there some CKeditor configuration file elog is defering to that I've overlooked? I have tried system wide seaches just in case.
