Template not linking to hosts

[guille_pm]

I've just installed Zabbix and I'm playing around with it (for now). I created a couple of hosts, imported a template for the IBM i (what I need to monitor) but I can't seem to link a template to a host.
I created a different host, another CentOS, but I still can't link a template to that one either even though that, for all cases, I get the "Host updated" message.

I've been doing some reading on it, and some articles said it could be due to php resource limits. I set the following

max_input_vars = 5000
memory_limit = 1024M

Still same thing happens, and no errors are logged to /var/log/httpd/error_log.

I made a test to see if error would be logged and reduced the memory size to 256 kb, and got some errors logged

So, bottomline, I get the message "Host updated", I see no errors logged, but still the templates are not linked to the host.

Maybe I'm doing something wrong, but I've read the documentation and followed the steps...

Just tried, for the sake os testing itself, to add another template to my Zabbix Server (which already has templates linked). I got the message "Host updated", but the template was not linked.

Hello. I'm no expert by any means, but I can create a host and add the template at that time (or later) and it is linked. Any chance it could be a browser cache issue?

I'm currently using Chrome. I just tried Firefox, same thing.

Maybe you could note your Zabbix server environment and version and someone with similar may be able to help more. I'm just using the prebuilt Hyper-V VHD 4.4.6 version myself and seems to work fine but still no cakewalk.

I'm using Zabbix 4.0.19 on a Centos7 machine.

I saw in your #1 user post that you may have had to compile things yourself? Or were you able to muddle through without? Ignore as needed.

Would i be able to make a host and include the format around then (or later) and it is connected. Any possibility it could be a program reserve issue.

I have the same problem as the author of this post. Have Zabbix 4.0.27 on Redhat 8 Enterprise server.

Does anyone have a solution to solve this wierd issue?
