Why is "function is_themler_preview" called on frontend ?

Then second bug, much more problematic. Each time saving something in Themler activate Themler core plugin again-
It should be fixed as soon as possible.

Hello Stagger Lee,
I'm sorry but both issues are not quite clear. Could you please describe them in more details?

1. When plugin from link is installed. All works OK until you try to download attachment from Post. Default theme doesnt make same problem, only TH theme.

2. • Go to plugin management in WP.
   • Disable Themler core plugin.
   • Go to the Themler editing screen and click "Save" button.
   • Themler core plugin is enabled again.

It shoull respect User´s choice and not activate Themler core plugin again on each Save.

I mean if you call function "is_themler_preview" only in backend this problem is solved. I dont see need for it on frontend.
Dont know now why it makes problems with this plugin. But restricting it to backend seems as quick solution, to not to lose much time on it.

Hello Stagger Lee,
thank you for details.
I'm passing both issue to developers for review and we'll contact you when solution is available.

Hello Stagger Lee,
to make the Download Attachments plugin working please edit the file

\wp-content\plugins\themler-core\themler-core.php

find the code block

require_once 'functions.php';

if (!class_exists('ShortcodesUtility') && !is_themler_preview() && !is_themler_action()) {
    require_once 'shortcodes/shortcodes.php';
}

and replace it with

require_once(dirname(__FILE__) . '/functions.php');

if (!class_exists('ShortcodesUtility') && !is_themler_preview() && !is_themler_action()) {
    require_once(dirname(__FILE__) . '/shortcodes/shortcodes.php');
}

It is temporary solution. Permanent fix will be included into the next Themler update
