Hello,

When I want to view tags, I get an error. It doesn't work from the plain user view nor admin (ex. /admin.php?page=tags)

I get the same error.

Code:

Fatal error: Uncaught --> Smarty: Unable to load 'file:include/selected_tags.inc.tpl' <-- thrown in /app/www/public/include/smarty/src/Template.php on line 159

Currently it's modus, but changing it didn't resolve the issue.
I tried to change it to bootstrap_darkroom and stripped_responsive and I get the same error.
I also noticed some warnings in the profile.php page of the user

Even with now having updated to Currently running version 16.2.0, I'm still unable to use tags and see errors when I try

Hi :-)

Have you checked that the requested file is present?

Sorry for the late response

Code:

root@740519cd9d2e:/# find . -path ./proc -prune -o -type f -name 'selected_tags.inc.tpl*' -print
./config/www/themes/smartpocket/template/include/selected_tags.inc.tpl

I used AI and this change to the file /app/www/public/include/selected_tags.inc.php, inside the piwigo container fixed the issue:

changed this:

Code:

$template->set_filename('selected_tags', 'include/selected_tags.inc.tpl');

to this:

Code:

$template->set_filename(
  'selected_tags',
  'themes/smartpocket/template/include/selected_tags.inc.tpl'
);

This was just a proof of concept, and I hope this will help you figure out what's wrong, to be able to fix it correctly, but exploring the albums from Tags simply works now with this fix.

I'm also hitting this, on piwigo 16.2.0

I only see it on mobile - I'm not sure how the theme gets set for that.

I tried the change epifeny posted but it didn't fix the problem for me.

With stack:

Code:

 Fatal error: Uncaught --> Smarty: Unable to load 'file:include/selected_tags.inc.tpl'

OK, this change worked for me:

Have you checked that the requested file is present?

Would you be able to check this issue out?

Use FTP to check whether the file is present (I don't have access to it.)

I provided the details for that above. Please see my previous detailed responses.

ddtddt can you help here?

A fix was made 2 months ago too add the missing tpl file to smartpocket. This was published with the version 16.1.0.1 of the theme.

I am unable to reproduce the problem on my end, can anyone provide more details ?

Is your version of smartPocket up to date?

Yes, smartPocket is up to date. From themes/smartpocket/themeconf.inc.php: Version: 16.2.0.

The file exists at themes/smartpocket/template/include/selected_tags.inc.tpl (starts with <span id="selected-tags-container">).

The problem is in core: include/selected_tags.inc.php has:

Code:

$template->set_filename('selected_tags', 'include/selected_tags.inc.tpl')

with no fallback, so themes without that file fail.

I changed it to

Code:

$template->set_filename('selected_tags', 'themes/smartpocket/template/include/selected_tags.inc.tpl')

and tags work again.

The proper fix should be in core with a fallback to the default theme.
