Hi

i've read that modus would be the new default theme. Ok - it looks nice - i want to use it :). Modus exists for 2.9.5 - ok - i want make some changes in header.tpl (footer.tpl, ...).

At the moment i use a clone of "elegant". I've changed ONLY 2 .tpl-Files. I have the same plan with modus. But i have a problem to clone this theme.

My Todo:
* create a new directory
** copy themeconf.inc.php, index.php to this dir.
* create sub-dir: template
** copy the tpl

=> no configiguration in Admin/Themes-Menu.

Ok i must copy /admin/ to my Clone
=> Error (missing functions.inc.php)
Ok functions.inc.php
=> Works

But it don't work @ the frontend - some errors

Warning: filemtime(): stat failed for ./themes/fotobastler_v2/css/base.css.tpl in /****/include/template.class.php on line 1894
[...]
Fatal error: Uncaught --> Smarty: Missing template name <-- thrown in /****/include/smarty/libs/sysplugins/smarty_template_source.php on line 157


My themeconf.inc.php

$themeconf = array(
'name' => 'fotobastler_v2',
'parent' => 'modus',
);

No other changes @ the moment.

I could copy /css/ from modus to my theme ... but what happend with changes in new versions of modus? Not a good idea?

What am i doing wrong?
Piwigo version: 2.9.5
PHP version: 7.3

Thanks
