[Koha] Upgrade to 21.11 - problems with extensions (coverflow and Koha as a CMS)

[Isabel Pineda]

Hi.

I know that the extensions are not strictly a part of Koha, but maybe someone can help me with this:

I am using the Coverflow plugin and the additional "pages" template to use Koha as a CMS. These things worked for me in previous Koha versions but stopped working after the upgrade to 21.11:

-          The Coverflow is not showing (only the "loading ..." text is there).

-          The content of the custom pages is not showing.

-          There is no error message in the web console.

-          The opac-error.log shows me a repeated error about the use of an uninitialized value in the file /usr/share/koha/lib/C4/XSLT.pm, but I don't know if this error has something to do with my problem.


What I did after the upgrade:

-          For Coverflow: I updated the Coverflow plugin to the latest version (2.5.0).

-          For Koha as a CMS: I overwrote the old file pages.pl with a copy of the new file opac-main.pl and followed the instructions for this file at https://koha-community.org/manual/21.11/en/html/extending_koha.html#using-koha-as-a-content-management-system-cms

-          For Koha as a CMS: I overwrote the old file pages.tt with a copy of the new file opac-main.tt and tried to follow the instructions for this file at https://koha-community.org/manual/21.11/en/html/extending_koha.html#using-koha-as-a-content-management-system-cms, but the line that has to be modified has changed, so here I don't know how to do it. But at least the content of my custom pages ought to appear without changing the template, I think that something must be wrong in the file pages.pl.

Is there anybody who is using these extensions and can help me?

Thank you very much.
