The issue is not resolved. We have placed these three files in place on our site. Then when going to an article page, where the issue can be seen, the page was now broken with this error:
Cannot use object of type stdClass as array
I found the problem was in this file:
[root]/templates/ja_teline_v/html/layouts/joomla/content/image/intro.php
I fixed it by replacing:
if (!empty($displayData['params'])) {
$aparams = $displayData['params'];
$forceIntro = $aparams->get('forceIntro');
}
with...
if (!empty($displayData->params)) {
$aparams = $displayData->params;
$forceIntro = $aparams->get('forceIntro');
}
Now, the new error is gone, but the initial problem remains. Remember, the problem is only in the display of the image within the module, nowhere else. AND, it displays fine on the home page, category pages, etc. It breaks when viewing any regular article page.
