Title: Plugin slow down webiste Last modified: February 29, 2020 --- # Plugin slow down webiste * Resolved [capabomba](https://wordpress.org/support/users/capabomba/) * (@capabomba) * [6 years, 3 months ago](https://wordpress.org/support/topic/plugin-slow-down-webiste/) * Hello, Yuzo plugin is giving me trouble on this website and I had to deactivate it. Webpages from desktop would load very slowly, while from mobile it would not even complete the request. * By deactivating it, the website works normally. I’m wondering what might be the reason. From my debug log I see these errors: * ``` [07-Feb-2020 11:59:22 UTC] PHP Notice: unserialize(): Error at offset 124 of 3497 bytes in /web/htdocs/www.ecostiera.it/home/wp-content/plugins/yuzo-related-post/public/classes/class-display.php on line 99 [07-Feb-2020 11:59:22 UTC] PHP Notice: Undefined property: stdClass::$fieldset_design in /web/htdocs/www.ecostiera.it/home/wp-content/plugins/yuzo-related-post/public/classes/class-related.php on line 1069 [07-Feb-2020 11:59:22 UTC] PHP Notice: Undefined property: stdClass::$fieldset_design in /web/htdocs/www.ecostiera.it/home/wp-content/plugins/yuzo-related-post/public/classes/class-related.php on line 1073 [07-Feb-2020 11:59:22 UTC] PHP Notice: Undefined property: stdClass::$design_screen_mobile in /web/htdocs/www.ecostiera.it/home/wp-content/plugins/yuzo-related-post/public/classes/class-related.php on line 1073 [07-Feb-2020 11:59:22 UTC] PHP Notice: Undefined index: design_screen_tablet in /web/htdocs/www.ecostiera.it/home/wp-content/plugins/yuzo-related-post/public/classes/class-related.php on line 1074 [07-Feb-2020 11:59:22 UTC] PHP Notice: Undefined property: stdClass::$design_screen_tablet in /web/htdocs/www.ecostiera.it/home/wp-content/plugins/yuzo-related-post/public/classes/class-related.php on line 1074 [07-Feb-2020 11:59:22 UTC] PHP Notice: Undefined index: design_screen_desktop in /web/htdocs/www.ecostiera.it/home/wp-content/plugins/yuzo-related-post/public/classes/class-related.php on line 1075 [07-Feb-2020 11:59:22 UTC] PHP Notice: Undefined property: stdClass::$design_screen_desktop in /web/htdocs/www.ecostiera.it/home/wp-content/plugins/yuzo-related-post/public/classes/class-related.php on line 1075 [07-Feb-2020 11:59:22 UTC] PHP Notice: Undefined index: template_type in /web/htdocs/www.ecostiera.it/home/wp-content/plugins/yuzo-related-post/public/classes/class-template.php on line 623 [07-Feb-2020 11:59:22 UTC] PHP Notice: Undefined index: design_image_size in /web/htdocs/www.ecostiera.it/home/wp-content/plugins/yuzo-related-post/public/classes/class-template.php on line 440 [07-Feb-2020 11:59:22 UTC] PHP Notice: Undefined index: template in /web/htdocs/www.ecostiera.it/home/wp-content/plugins/yuzo-related-post/public/classes/class-template.php on line 455 ``` * The plugin is currently deactivated. - This topic was modified 6 years, 3 months ago by [capabomba](https://wordpress.org/support/users/capabomba/). - This topic was modified 6 years, 3 months ago by [capabomba](https://wordpress.org/support/users/capabomba/). * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fplugin-slow-down-webiste%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 3 replies - 1 through 3 (of 3 total) * Thread Starter [capabomba](https://wordpress.org/support/users/capabomba/) * (@capabomba) * [6 years, 3 months ago](https://wordpress.org/support/topic/plugin-slow-down-webiste/#post-12410624) * Dear Lenin, thanks for your reply. The website is already running on PHP 7.1. I have to say the website already has some performance issues but when Yuzo is activated it’s not only about loading speed of pages, but in the mobile version it makes it impossible to reach pages at all. I haven’t tried with a cache plugin but that will take some time to implement. Meanwhile is there any more troubleshooting that you would recommend? * Why is there a error with unserialize? Thank you for you * Plugin Contributor [ilenstudio](https://wordpress.org/support/users/ilenstudio/) * (@ilenstudio) * [6 years, 3 months ago](https://wordpress.org/support/topic/plugin-slow-down-webiste/#post-12410658) * It is strange, for example, the first error that you show is in this file on line 99 which is about unserialize. 🖼️ [screenshot](https://i.imgur.com/YKzGNKr.png) In no other website I have found that this line has problems and what it does is that the code that you have saved from the configuration of **Yuzo **is transformed into an array or valid object to be able to manipulate the options, as `you see nothing special` or anything else world in that code but it sends you a half odd mistake. * Maybe it’s your hosting problem, maybe you try _Yuzo _in another instance of Hosting and draw your conclusions, that if a **Cache plugin** saved you a lot of things, you need to use it. I recommend for the moment to use [https://wordpress.org/plugins/wp-fastest-cache/](https://wordpress.org/plugins/wp-fastest-cache/) With **Yuzo ** it works very well and your website will go faster. * Thread Starter [capabomba](https://wordpress.org/support/users/capabomba/) * (@capabomba) * [6 years, 3 months ago](https://wordpress.org/support/topic/plugin-slow-down-webiste/#post-12410694) * Ok I’ll try that and get back to you.
