First obvious question, if you deactivate Link Library and try to save options in another plugin, do you still get these warnings? They might just not appear on-screen, but might still happen. A better way to check warnings is to activate the WP_DEBUG_LOG option in your wp-config.php file. Then, a file called debug. log will be created in your site’s wp-content folder. When this is in place, deactivate Link Library, and save another plugin’s settings, seeing if new entries still appear in the log. * Thread Starter [darekk2](https://wordpress.org/support/users/darekk2/) * (@darekk2) * [7 years, 10 months ago](https://wordpress.org/support/topic/link-library-on-the-localhost/#post-10491823) * Oh my, Yet another Star Rating interferes again with Link Library configuration. But theoretically it should be absent in configuration forms of the Link Library. But the [Re-import liks] button works in the internet (not the localhost). So this is something new. * Options in other plugins seem to work well, and most of options in the Link Library. Except “Global Configuration” / “Library Configurations”. * I changed `define('WP_DEBUG', false);` from false to true in the localhost, but the debug.log did not appear. Thre is only such file in the link-library category, containing something not important probably: * ``` [SOCIAL - 2013-01-17 03:00:41 - 173.179.80.106] Checking system CRON [SOCIAL - 2013-01-17 03:00:42 - 173.179.80.106] Running request: Settings/action_index ``` * However such new information is displayed above `( ! ) Warning: Invalid argument supplied ...` after pressing the [Re-import liks] button: * ``` Błąd bazy danych WordPressa: [Unknown column 'le.link_addl_rel' in 'field list'] SELECT distinct l.link_id as import_link_id, l.link_name, l.link_url, l.link_rss, l.link_description, l.link_notes, GROUP_CONCAT( t.name ) as cat_name, l.link_visible, le.link_second_url, le.link_telephone, le.link_email, le.link_reciprocal, l.link_image, le.link_textfield, le.link_no_follow, l.link_rating, l.link_target, l.link_updated, le.link_visits, le.link_submitter, le.link_submitter_name, le.link_submitter_email, le.link_addl_rel, le.link_featured, le.link_manual_updated, l.link_owner FROM wp_terms t LEFT JOIN wp_term_taxonomy tt ON (t.term_id = tt.term_id) LEFT JOIN wp_term_relationships tr ON (tt.term_taxonomy_id = tr.term_taxonomy_id) LEFT JOIN wp_links l ON (tr.object_id = l.link_id) LEFT JOIN wp_links_extrainfo le ON (l.link_id = le.link_id) WHERE tt.taxonomy = 'link_category' GROUP BY l.link_id ``` * During changing options on localhost `( ! ) Warning: Invalid argument supplied...` messages are displayed. * Thread Starter [darekk2](https://wordpress.org/support/users/darekk2/) * (@darekk2) * [7 years, 10 months ago](https://wordpress.org/support/topic/link-library-on-the-localhost/#post-10491840) * The debug.log did not appear in the internet (not localhost) wp-content folder either.

But if you save another plugin’s settings and check the logs, does YASR still produce these warnings in the log file. * – For the re-import not working through, it looks like you might not have been running the most recent version of Link Library 5.9 before updating to 6.0, since the error message talks about a column I had added recently. Remove the 6.0 version and install the last version of 5.9 ([https://downloads.wordpress.org/plugin/link-library.LinkLibrary_5.9.15.8.zip](https://downloads.wordpress.org/plugin/link-library.LinkLibrary_5.9.15.8.zip)). Then, deactivate and reactivate that version to make sure that your tables are up-to-date. Then, go back to latest 6.0 version and try re-import.
