Please do the following:
1.
De- activate all other plugins temporary, and test the photo albums page. If it works, activate the other plugins one by one and test the page after each activation (press CTRL+F5 to refresh the browser).
Remenmber the plugin whose activation caused the fail and tell me so.
2.
If de-actvation of all other plugins failed to get the photo albums page to work, do the following:
Go to the Edit tab of the Plugins menu of the left sidebar in the admin screen.
Select plugin to edit WP Photo Album Plus in the right sidebar.
Click on file wp-photo-album-plus/wppa-filter.php
You will see this:
<?php
/* wppa-filter.php
* Package: wp-photo-album-plus
*
* get the albums via filter
* version 4.0.0
*
*/
add_action('init', 'wppa_do_filter');
function wppa_do_filter() {
add_filter('the_content', 'wppa_albums_filter', 10);
}
function wppa_albums_filter($post) {
global $wppa;
$post_old = $post;
$post_new = '';
.
.
.
.
please change
add_filter('the_content', 'wppa_albums_filter', 10);
into (change 10 to 1)
add_filter('the_content', 'wppa_albums_filter', 1);
and press Update File
This should result in the album(s) being displayed.
However, if it works, it is NOT a solution (the layout will be wrong), but i am eager to know this.
