Title: Examples plugin page does not open Last modified: March 27, 2024 --- # Examples plugin page does not open * Resolved [martinnartub](https://wordpress.org/support/users/martinnartub/) * (@martinnartub) * [2 years, 2 months ago](https://wordpress.org/support/topic/examples-plugin-page-does-not-open/) * I’m getting this error message when I try to open the Documentation/examples plugins. This happens only on the 3.14 version. On my previous version worked pretty well. Is there any alternative way to install a MLA UI Elements Example without through the Example Plugins page?Fatal error: Uncaught TypeError: uasort(): Argument #2 ($callback) must be a valid callback, class MLASettings_Documentation does not have a method “_sort_uname_callback” in /Users/machine/Local Sites/theme- fixes/app/public/wp-content/plugins/media-library-assistant/includes/class-mla- settings-documentation-tab.php:1187 Stack trace: #0 /Users/machine/Local Sites/ theme-fixes/app/public/wp-content/plugins/media-library-assistant/includes/class- mla-settings-documentation-tab.php(1187): uasort(Array, ‘MLASettings_Doc…’) # 1 /Users/machine/Local Sites/theme-fixes/app/public/wp-content/plugins/media- library-assistant/includes/class-mla-settings-documentation-tab.php(1333): MLA_Example_List_Table:: _get_example_plugin_items() #2 /Users/machine/Local Sites/theme-fixes/app/public/ wp-content/plugins/media-library-assistant/includes/class-mla-settings-documentation- tab.php(1445): MLA_Example_List_Table::_execute_example_items_query(Array) #3/ Users/machine/Local Sites/theme-fixes/app/public/wp-content/plugins/media-library- assistant/includes/class-mla-settings-documentation-tab.php(887): MLA_Example_List_Table:: _count_example_items(Array) #4 /Users/machine/Local Sites/theme-fixes/app/public/ wp-content/plugins/media-library-assistant/includes/class-mla-settings-documentation- tab.php(189): MLA_Example_List_Table->prepare_items() #5 /Users/machine/Local Sites/theme-fixes/app/public/wp-content/plugins/media-library-assistant/includes/ class-mla-settings-documentation-tab.php(242): MLASettings_Documentation::_compose_example_tab()# 6 /Users/machine/Local Sites/theme-fixes/app/public/wp-content/plugins/media- library-assistant/includes/class-mla-settings.php(1584): MLASettings_Documentation:: mla_compose_documentation_tab() #7 /Users/machine/Local Sites/theme-fixes/app/ public/wp-includes/class-wp-hook.php(324): MLASettings::mla_render_settings_page(”)# 8 /Users/machine/Local Sites/theme-fixes/app/public/wp-includes/class-wp-hook. php(348): WP_Hook->apply_filters(”, Array) #9 /Users/machine/Local Sites/theme- fixes/app/public/wp-includes/plugin.php(517): WP_Hook->do_action(Array) #10 / Users/machine/Local Sites/theme-fixes/app/public/wp-admin/admin.php(259): do_action(‘ settings_page_m…’) #11 /Users/machine/Local Sites/theme-fixes/app/public/wp-admin/ options-general.php(10): require_once(‘/Users/martinsi…’) #12 {main} thrown in/ Users/machine/Local Sites/theme-fixes/app/public/wp-content/plugins/media-library- assistant/includes/class-mla-settings-documentation-tab.php on line 1187 - This topic was modified 2 years, 2 months ago by [martinnartub](https://wordpress.org/support/users/martinnartub/).
