Hi Gina,

Everything is working now, thanks to you. I did everything you said but I still had small errors.
If you updated to the latest version and the following error appears when you try to launch Themler please follow the instruction below:

Fatal error: require_once(): Failed opening required '[...]/administrator/includes/toolbar.php' (include_path='.:/usr/lib/php7.2') in [...]/templates/[theme_name]/app/index.php on line 25

Open theme folder on the server: www/Joomla_directory/templates;
open /app folder;
open index.php for editing in any html or text editor;
find the line
require_once JPATH_BASE . DS . 'includes' . DS . 'toolbar.php';
and replace it with the following line:
$prefix = version_compare(JVERSION, '3.9', '>=') ? 'sub' : '';
require_once JPATH_BASE . DS . 'includes' . DS . $prefix . 'toolbar.php';;
open /app/start folder;
open data.php file for editing and follow step 4;
open manifest.php file for editing and follow step 4;

First option: access your site via FTP , go to templates folder and copy current theme.
Zip it on your computer and open it with Themler desktop, then update.

Second option: we can try to continue changing php files manually.
open file ExportController.php (directory is shown in the error message).

Open app/classes/ExportController.php file and find this line (433):
$func = create_function("", "echo json_encode(array(error => 'memtest'));");

Replace it with
$func = function () {
echo json_encode(array(error => 'memtest'));
};

then I downloaded the template folder via ftp
then compressed the folder as zip
then started Themler in Windows and imported the zip file
The theme was automatically updated to the new version
and then clicked explicitly on the button next to Home on Update (was updated again)
then export as zip and entered a new theme name
then installed the new theme in Joomla.
and was able to open and edit it without any problems
Thanks Gina, it wouldn't have worked without your help

thx :-)

Marco,

1. First option: access your site via FTP , go to templates folder and copy current theme.
   Zip it on your computer and open it with Themler desktop, then update.

2. Second option: we can try to continue changing php files manually.
   open file ExportController.php (directory is shown in the error message).

Open app/classes/ExportController.php file and find this line (433):

  $func = create_function("", "echo json_encode(array(error => 'memtest'));");

Replace it with

  $func = function () {
        echo json_encode(array(error => 'memtest'));
    };

Thank you Gina for your prompt reply.
