Maybe something is off there. * Plugin Author [Scrollsequence](https://wordpress.org/support/users/scrollsequence/) * (@scrollsequence) * [4 years, 12 months ago](https://wordpress.org/support/topic/wordpress-crash-on-activate/#post-14540821) * I suspect there may be a conflict with some of the plugins. * Divi theme works fine with Scrollsequence. Akismet, Divi, Elementor and Elementor PRO are fine and tested too. * Try disabling the other ones and activating Scrollsequence again. * On my end I will try to recreate your setup, please allow some time for setting up. * Ales * Thread Starter [mido9790](https://wordpress.org/support/users/mido9790/) * (@mido9790) * [4 years, 12 months ago](https://wordpress.org/support/topic/wordpress-crash-on-activate/#post-14540863) * Hello Ales, * I have deactivated and deleted all of the other plugins and only left the 4 you mentioned. * It is still causing the same issue. * “There has been a critical error on this website. Please check your site admin email inbox for instructions” * I am using apache 2 ubuntu 20.04 for my linux server. * As I have mentioned before, if there are any specific settings that need to be set in the linux server from the php side, or in WordPress, let me know. * I like your plugin and will gladly assist to find any bugs. * Mido * Plugin Author [Scrollsequence](https://wordpress.org/support/users/scrollsequence/) * (@scrollsequence) * [4 years, 12 months ago](https://wordpress.org/support/topic/wordpress-crash-on-activate/#post-14540988) * Okay, so I have installed all the plugins I could find on a clean TwentyTwentyOne theme (don’t have access to Divi, but I know this theme works fine). * After I have activated the following plugins: Akismet, Elementor, Make Column Clickable Elementor, Mighty Addons, myStickymenu, PowerPack Lite for Elementor, Starter Templates and WP-VideoScroll and then tried to activate and deactivate Scrollsequence (FREE version). * All worked fine, there are no conflicts from what I can see. * Regarding running on Linux server – I have no experience in that, so I cannot give any advice on what might be the issue. * Few ideas: * 1) Have you tried turning WP_debug to true? [https://codex.wordpress.org/WP_DEBUG](https://codex.wordpress.org/WP_DEBUG) This should give more information when throwing errors. 2) Could you please go to wp-admin -> Tools -> Site Health and send me the information from “Status” and “Info” tabs? This should give me more idea about the settings that you are working with. 3) It would be really beneficial if we could work on the same installation, do you have any public server available that we could both access? If not, I have a spare server, but I know that things will be working on there * EDIT: 4) Did you have a look in your email? Sometimes is gives a bit more information in the admin email * Thank you for your input, I hope we will find a solution soon! * Ales - This reply was modified 4 years, 12 months ago by [Scrollsequence](https://wordpress.org/support/users/scrollsequence/). * Thread Starter [mido9790](https://wordpress.org/support/users/mido9790/) * (@mido9790) * [4 years, 12 months ago](https://wordpress.org/support/topic/wordpress-crash-on-activate/#post-14541026) * Hi Ales, * I went to the site health, and yes, some stuff is missing. Can you let me know if any of these are crucial? If yes, I will install them on my server. * ``` 1 critical issue One or more required modules are missing Performance PHP modules perform most of the tasks on the server that make your site run.

They are basically saying, that mb_convert_case() is missing. * I wonder if it’s because the missing “mbstring” module? * My suggestion is to activate the optional modules and try again. * Fingers crossed! * Ales - This reply was modified 4 years, 12 months ago by [Scrollsequence](https://wordpress.org/support/users/scrollsequence/). * Thread Starter [mido9790](https://wordpress.org/support/users/mido9790/) * (@mido9790) * [4 years, 12 months ago](https://wordpress.org/support/topic/wordpress-crash-on-activate/#post-14541559) * Hi Ales, * I have installed the missing modules and the plugin is correctly working now. * A small suggestion would be to mention the mbstring module and any other required modules as a requirement in the description before you install the plugin, and maybe also give some instructions for installation on the plugin page. It would help others out. * Thank you for your amazing support! * Mido * Plugin Author [Scrollsequence](https://wordpress.org/support/users/scrollsequence/) * (@scrollsequence) * [4 years, 12 months ago](https://wordpress.org/support/topic/wordpress-crash-on-activate/#post-14541827) * **Happy Days! ** * Yes, it would make sense to have that in writing and documentation, will add it. * Thanks for cooperation and happy animating!
