Title: Plugin Conflict Last modified: April 7, 2026 --- # Plugin Conflict * Resolved [whitelily85](https://wordpress.org/support/users/whitelily85/) * (@whitelily85) * [2 months ago](https://wordpress.org/support/topic/plugin-conflict-461/) * Hi, I have been using this plugin for a while now, many thanks. Unfortunately since the last update I am having an issue. I can’t update any page on my website, without first deactivating the plugin. If the plugin is activated and I click on edit page, I only get a blank page. If the plugin is deactivated, I can edit pages as normal.No issues at the front end. And after updating the content, I activate the plugin again and all the hfrelangs works again. The issue only happens with Pages, not with Posts.Is this a known issue and is there any solution?Many thanks in advance. - This topic was modified 2 months ago by [whitelily85](https://wordpress.org/support/users/whitelily85/). * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fplugin-conflict-461%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 7 replies - 1 through 7 (of 7 total) * Plugin Author [Webnow](https://wordpress.org/support/users/webnow66/) * (@webnow66) * [2 months ago](https://wordpress.org/support/topic/plugin-conflict-461/#post-18873933) * Hello [@whitelily85](https://wordpress.org/support/users/whitelily85/) , could you please check if you have latest version **1.0.6** installed ? * Thread Starter [whitelily85](https://wordpress.org/support/users/whitelily85/) * (@whitelily85) * [2 months ago](https://wordpress.org/support/topic/plugin-conflict-461/#post-18874084) * Yes, it is the latest version, 1.0.6 * Plugin Author [Webnow](https://wordpress.org/support/users/webnow66/) * (@webnow66) * [2 months ago](https://wordpress.org/support/topic/plugin-conflict-461/#post-18874572) * [@whitelily85](https://wordpress.org/support/users/whitelily85/) is it possible if you can share some Error Logs, or a temporary login to your website ? * Thread Starter [whitelily85](https://wordpress.org/support/users/whitelily85/) * (@whitelily85) * [2 months ago](https://wordpress.org/support/topic/plugin-conflict-461/#post-18874814) * PHP Fatal error: Uncaught TypeError: unserialize(): Argument #1 ($data) must be of type string, array given in /home/customer/www/realronda.com/public_html/ en/wp-content/plugins/hreflang-tags-management/admin/partials/hreflang-tags-management- meta-display.php:8 Stack trace: 0 /home/customer/www/realronda.com/public_html/ en/wp-content/plugins/hreflang-tags-management/admin/partials/hreflang-tags-management- meta-display.php(8): unserialize(Array) 1 /home/customer/www/realronda.com/public_html/ en/wp-content/plugins/hreflang-tags-management/admin/class-hreflang-tags-management- admin.php(209): require_once(‘/home/customer/…’) 2 /home/customer/www/realronda. com/public_html/en/wp-admin/includes/template.php(1453): HreflangTagsMgmtAdmin- >hreflang_tags_mgmt_management_display_callback(Object(WP_Post), Array) 3 /home/ customer/www/realronda.com/public_html/en/wp-admin/includes/post.php(2400): do_meta_boxes( Object(WP_Screen), ‘normal’, Object(WP_Post)) 4 /home/customer/www/realronda. com/public_html/en/wp-admin/edit-form-blocks.php(383): the_block_editor_meta_boxes() 5 /home/customer/www/realronda.com/public_html/en/wp-admin/post.php(187): require(‘/ home/customer/…’) 6 {main} * thrown in /home/customer/www/realronda.com/public_html/en/wp-content/plugins/ hreflang-tags-management/admin/partials/hreflang-tags-management-meta-display. php on line 8 * Plugin Author [Webnow](https://wordpress.org/support/users/webnow66/) * (@webnow66) * [2 months ago](https://wordpress.org/support/topic/plugin-conflict-461/#post-18875692) * Thanks for providing error logs [@whitelily85](https://wordpress.org/support/users/whitelily85/) We have deployed the fix with latest version 1.0.7Please update the plugin and let us know if your issue gets resolved. * Thread Starter [whitelily85](https://wordpress.org/support/users/whitelily85/) * (@whitelily85) * [2 months ago](https://wordpress.org/support/topic/plugin-conflict-461/#post-18875974) * Hi, I updated and now have version 1.0.8 active.
