Unfortunately HTTP->HTTPS redirection breaks ModPagespeed 😟 I haven't figured out how to work around it yet.

I suspect HSTS will introduce the same problem with Pagespeed.

Looks like Linode does not support DNSSEC yet. I only added the CAA record πŸ˜‰
What do you do if you constantly receive annoying repetitive non-SPAM mails? I usually delete them. Months or years of daily annoying repetitive unnecessary activities eat our health and life, but we still do it, don't we?

So, yesterday I fixed the web-logging processing script that broke 3 years ago after automatic upgrading PERL to 5.26 (left curly brackets must be escaped with back-slash now)

Today I checked the now working statistics and discovered a huge amount of requests to non-existing files, and fixed another problem which appeared years ago after upgrading the forum software (GIF pictograms were replaced with PNG ones, but the links were not updated). Both the page load time and search engine penalties should decrease as a result.

Step for step πŸ˜‰
Hmm... getting some odd responses when posting or trying to post today.

Messages about possible security issues or else saying I've aeady posted, but then either everything is fine or else the post is lost and I have to re-do from scratch.

Most strange...

Hm... This is something what was not changed last night. I only removed references to non-existing files and renamed incorrect links. Could you please make a screen shot of those messages, if you encounter them again? You are using Edge, right? (I have access to Windows 7 only, so no Edge).
Replaced jQuery with the latest version, and "suddenly" the mobile version of the blog started working properly on iPhone. Also, version 3.3.1 is the first >2 version that works properly with the forum. Whatever I tried earlier used to break something. As a bonus, Google auditor does not show, that the site contains a vulnerable library (which is used by default by WordPress!). Nice! πŸ˜‰

But please let me know if posting is working correctly for everybody. I cleaned the cache up, so there shouln'd be any risiduals.

But now it's broken on Android 😁

Ah...Fixed..

And, as it appeared, still does not work. The problem is, the combination of jQuery >2.1 and Mod_PageSpeed breaks Edit -> Quick Edit. If I disable PageSpeed or downgrade jQuery - it works. For some weird reasons the mobile behaviour differs from the desktop one, though there should not be any difference (there is no mobile version of the forum). I've been debugging and troubleshooting (for many hours aeady 😐 ), so you might encounter some glitches.
OK, it was "defer_javascript" PageSpeed filter. Some kind of a race condition. Let's call it fixed for the time being. I wonder what effect this filter has on the page load.

Edit: either no effect, or now (with a new combination of filters and tweaks) it works faster. No more tweaking for tonight. Let me know if anything is broken.
Lots of other small fixes and plugin updates today. Still scared to make serious but necessary changes, though getting closer πŸ˜‰

This is what a dev/sandbox environment is for. Backup a copy of this server, spin it up on a seperate machine, test the changes/updates and see what breaks.
