[Koha] Coverflow on Koha 18.05

[Mai]

Hi everybody, does anybody know if Coverflow Plugin works on Koha 18.05?
We are currently working with Koha 16.11 on Debian 8, where it works just
fine; but we are setting up a new installation in another server and we
took the opportunity to switch to 18.05, on a Debian 8 as well.
We've ckecked that both the instance's apache configuration file and
koha-conf.xml are configured with the same parameters.
Coverflow calls to an existing report and the report returns results when
ran.
We've tried both with the latest Coverflow version on gitHub and with the
one that is currently working correctly on our 16.11 install.

My opac error log looks like this:

> [Fri Aug 03 16:35:46.547948 2018] [access_compat:error] [pid 32723]
> [client 192.168.51.79:52779] AH01797: client denied by server

> 16:35:46.54794$


And my apache error log:

> [Tue Aug 07 06:25:47.216361 2018] [ssl:warn] [pid 31995] AH01906:
> DEV-CAC-0024.cnea.ar:443:0 server certificate is a CA certificate
> (BasicConstraints: CA == TRUE !?)

[Tue Aug 07 06:25:47.216428 2018] [ssl:warn] [pid 31995] AH01909:
> DEV-CAC-0024.cnea.ar:443:0 server certificate does NOT include an ID
> which matches the server name


Could anybody give me a hand?
Thanks in advance!
