I have both extensions running on php 7.2.17. The extensions were bundled with that version.
The caveat is that my development server is a windows IIS machine.
I.e. it is not dead but you have to have a php.ini file that loads the extension. To do that you have to know the path extensions.

I have the same problem that you have on my production server but the php version is 7.3.10 -
The host ts&d says they are not available on that version (they are included). But b2evo does not find them and gives that same message.

I wish a php guru would join this discussion.

Hello,

The following frequent issues seem to apply to your support request: (This is a semi-automated response):

• You did not provide the Name / URL of your webhost (as requested for support + we want to catalog common hosts vs commons issues)

Sorry! Don't know why that link was in there. The problem is always Bluehost

we'll have to check the code and see if bluehost really was able to disable APC :/

It is no longer an issue for me because I dumped Bluehost and went to A2hosting. All the issues that I have raised disappeared. I understand that your point of view is different than mine. You need web hosts for the future of b2evo and for that reason you need to resolve this. I still have an account at Bluehost and if you need to set up a test site, I will help. I love b2evo and if I can be of use let me know. I would suggest a back channel for this.

knownhosts.com, VPS Package.

I have root access, if that helps.

@jjthomas Bluehost agrees with knownhosts.com (not on shared hosting) and this requires a considerable increase in costs. I moved my sites to A2hosting.com and have these extensions activated on their Turbo plan, at less costs. They are also decidedly faster as well. This is a no-brainer for me.

I'm not sure why setting up a cache would be costly.

There are too many variables to change a host over speed. One day my packets could go directly (not that the would really happen) to my host. The next day, the packets go via LA, NY, Nevada, Singapore and finally to my host. In so far as server response, with any shard hosting, i could end up sharing a server with amazon.com. If it gets bad, I can always ask my hosting provider to move me to another server. I think they do it anyway.

I've been with KnownHost for almost 13 years. I'm not going anywhere. :)

Hey there, similar problem, I use GreenGeeks, EcoSite Premium, Server Information:
Hostname: chi-pnode5.websitehostserver.net
IP: 184.154.57.34

I had this error:
PHP user cache: none
Using an user cache allows b2evolution to store some cached data (Block Cache) in memory instead of regenerated the blocks at each page load. Several user caches are available. We recommend APCu (which needs to be enabled separately from APC, starting from PHP 7).

I contacted them ("APCu extension has been enabled as recommended."), then we got this:

PHP opcode cache: none
Using an opcode cache allows all your PHP scripts to run faster by caching a "compiled" (opcode) version of the scripts instead of recompiling everything at every page load. Several opcode caches are available. We recommend APC (which is included with PHP starting from PHP 7).

PHP user cache: APCu

What should I tell my host to do now?

I was never able to solve the problem using Bluehost. I ended up changing to A2hosting. There I was able to get it working perfectly with the benefit of amazing speed.
