Now, I created a new page and I pasted the code as it says in this plugin page as follows:  [publications auth=all subj =articles] * My problems comes out when I visit my web page that says a lot of errors.

Try the following code: [publications auth=all subj=articles prep=all] Hope it’ll resolve your issue. * Thread Starter [kar95](https://wordpress.org/support/users/kar95/) * (@kar95) * [5 years, 8 months ago](https://wordpress.org/support/topic/fail-with-the-plugin/#post-13418884) * Hi [@frier](https://wordpress.org/support/users/frier/) , First of all thanks for responsing me.

I´m so happy about it. However, the plugin drastically slows down the access to my website. I don´t know if you can fix this but I completely believe in you 😀 * Kind regards, Carlos * Plugin Author [frier](https://wordpress.org/support/users/frier/) * (@frier) * [5 years, 7 months ago](https://wordpress.org/support/topic/fail-with-the-plugin/#post-13449361) * Hey [@kar95](https://wordpress.org/support/users/kar95/) ! Glad to hear that the plugin works fine! I tried to improve the performance in the newest update. I hope it will reduce the slow downs you experienced. * Thread Starter [kar95](https://wordpress.org/support/users/kar95/) * (@kar95) * [5 years, 7 months ago](https://wordpress.org/support/topic/fail-with-the-plugin/#post-13449882) * Hey [@frier](https://wordpress.org/support/users/frier/) ! I´m sorry that it still goes slowly. My web page is [https://mobilenet.uma.es/](https://mobilenet.uma.es/) in case you want to check the velocity of the connection. I`ve already checked that it´s this plugin the one which slows down the velocity experienced. * I don´t know how I can help you in order to make faster the plugin because it fits perfectly for this work. * I´ll be waiting your reply. Carlos * Plugin Author [frier](https://wordpress.org/support/users/frier/) * (@frier) * [5 years, 7 months ago](https://wordpress.org/support/topic/fail-with-the-plugin/#post-13453279) * So I tried to look for the plugin processes that can be sped up but at the moment I couldn’t find any. Also, I would be helpful if you can provide the time it takes to load page with and without plugin. It can be done through developer tools in your browser (usually it can be called by Ctrl+Shift+I combination). There find the network tab and reload the site page. When the page will be fully loaded you’ll see the time it took. I did this test on my site and it took (on average) 212 ms to load without plugin and 296 with it, which is an acceptable slow down. * Thread Starter [kar95](https://wordpress.org/support/users/kar95/) * (@kar95) * [5 years, 7 months ago](https://wordpress.org/support/topic/fail-with-the-plugin/#post-13453700) * Hi [@frier](https://wordpress.org/support/users/frier/) , With the plugin, the page takes almost 25.000 ms to load the page. And navigating through it (to another section almost 10.000 ms) In constrast, the page takes without the resources of your plugin, it takes less than 2.000 ms to load the main page and to another section like 1.500 ms. * If you need any screenshot or something, we can talk in private (by email) in order to try to fix this 🙂 * I´ll be looking forward your response Carlos * Plugin Author [frier](https://wordpress.org/support/users/frier/) * (@frier) * [5 years, 7 months ago](https://wordpress.org/support/topic/fail-with-the-plugin/#post-13459247) * Hey [@kar95](https://wordpress.org/support/users/kar95/) ! * In the newest update I have added some performance options to the plugin settings page under compatibility tab. Try ticking each of them and compare the page load time. It will disable some plugin functionality, but if you don’t use that particular functionality it should decrease the slow downs. Hope it will help you! * Thread Starter [kar95](https://wordpress.org/support/users/kar95/) * (@kar95) * [5 years, 7 months ago](https://wordpress.org/support/topic/fail-with-the-plugin/#post-13461781) * Hey [@frier](https://wordpress.org/support/users/frier/) , It works perfectly fine with the settings you give. I disable both of them and now it loads from almost 25.000 ms to around 1.5 seconds, that at least it´s something approachable to the web page. * Thanks for all the support you provided to me :D. I hope this plugin becomes one of the most downloaded in WordPress. * Thanks so much again. I´ve already rated this plugin with 5 stars 😉 Best regards, Carlos Viewing 11 replies - 1 through 11 (of 11 total) The topic ‘Fail with the plugin’ is closed to new replies. * ![](https://s.w.org/plugins/geopattern-icon/books-papers.svg) * [Books & Papers](https://wordpress.org/plugins/books-papers/) * [Frequently Asked Questions](https://wordpress.org/plugins/books-papers/#faq) * [Support Threads](https://wordpress.org/support/plugin/books-papers/) * [Active Topics](https://wordpress.org/support/plugin/books-papers/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/books-papers/unresolved/) * [Reviews](https://wordpress.org/support/plugin/books-papers/reviews/) * 11 replies * 2 participants * Last reply from: [kar95](https://wordpress.org/support/users/kar95/) * Last activity: [5 years, 7 months ago](https://wordpress.org/support/topic/fail-with-the-plugin/#post-13461781) * Status: not resolved
