Invision Community 4: SEO, prepare for v5 and dormant account notifications By Matt Monday at 02:04 PM
jwdenzel Posted June 1, 2022 Posted June 1, 2022 Hi there, my maintenance task cron job is failing. When I try to run it manually on the CLI I get the following error: # /usr/bin/php -d memory_limit=-1 -d max_execution_time=0 /var/www/html/applications/core/interface/task/task.php 710eec566b32f52cd33c9dfcd1824fdc PHP Fatal error: Uncaught Error: Call to undefined function IPS\mb_internal_encoding() in /var/www/html/init.php:556 Stack trace: #0 /var/www/html/init.php(1583): IPS\IPS::init() #1 /var/www/html/applications/core/interface/task/task.php(29): require_once('...') #2 {main} thrown in /var/www/html/init.php on line 556 I recently switched servers from an on-prem hardware solution to AWS instances. Everything else works fine, except I now get a giant warning that says my cron jobs are working. Help?
Jim M Posted June 1, 2022 Posted June 1, 2022 Please ensure that you have all required modules installed on that version of PHP. Currently, you're missing mb_string. Please use the following requirements checker and work with your server administrator to fix anything in red:https://invisioncommunity.com/files/file/7046-invision-community-requirements-checker/ jwdenzel 1
jwdenzel Posted June 1, 2022 Author Posted June 1, 2022 Thank you @Jim M. I must have had an older version of the requirements document. I installed mb_string and restarted Apache. Unfortunately I now get a different '500' error: # /usr/bin/php -d memory_limit=-1 -d max_execution_time=0 /var/www/html/applications/core/interface/task/task.php 710eec566b32f52cd33c9dfcd1824fdc <!DOCTYPE html> <html lang="en"> <head> <title>Error</title> <style type='text/css'> body { background: #f9f9f9; margin: 0; padding: 30px 20px; font-family: "Helvetica Neue", helvetica, arial, sans-serif; } #error { max-width: 800px; background: #fff; margin: 0 auto; } h1 { background: #151515; color: #fff; font-size: 22px; font-weight: 500; padding: 10px; } h1 span { color: #7a7a7a; font-size: 14px; font-weight: normal; } #content { padding: 20px; line-height: 1.6; } #reload_button { background: #151515; color: #fff; border: 0; line-height: 34px; padding: 0 15px; font-family: "Helvetica Neue", helvetica, arial, sans-serif; font-size: 14px; border-radius: 3px; } </style> </head> <body> <div id='error'> <h1>An error occurred <span>(500 Error)</span></h1> <div id='content'> We're sorry, but a temporary technical error has occurred which means we cannot display this site right now. <br><br> You can try again by clicking the button below, or try again later. <br><br> <button onclick="window.location.reload();" id='reload_button'>Try again</button> </div> </div> </body> The Apache logs don't show anything related to that 500 error. Is there a different log I can look at for more info? Any thoughts? Thank you
jwdenzel Posted June 1, 2022 Author Posted June 1, 2022 I found this in the application log: Wed, 01 Jun 2022 17:58:42 +0000 Error: Class "mysqli" not found (0) #0 /var/www/html/init.php(735): require_once() #1 /var/www/html/system/Data/Store/Database.php(92): IPS\IPS::autoloader() #2 /var/www/html/system/Data/Store/Database.php(108): IPS\Data\Store\_Database->loadIntoMemory() #3 /var/www/html/system/Data/Store/Database.php(162): IPS\Data\Store\_Database->get() #4 /var/www/html/system/Data/AbstractData.php(126): IPS\Data\Store\_Database->exists() #5 /var/www/html/system/Data/Store.php(303): IPS\Data\_AbstractData->__isset() #6 /var/www/html/system/Settings/Settings.php(176): IPS\Data\_Store->__isset() #7 /var/www/html/system/Settings/Settings.php(132): IPS\_Settings->loadFromDb() #8 /var/www/html/applications/core/interface/task/task.php(31): IPS\_Settings->__get() #9 {main} #0 /var/www/html/init.php(1015): IPS\_Log::log() #1 [internal function]: IPS\IPS::exceptionHandler() #2 {main} It says it can't find mysqli, but I verified that it is installed for my version of PHP (8.0.19) # apt-get install php8.0-mysqli Reading package lists...

Jim M Posted June 1, 2022 Posted June 1, 2022 Unfortunately, hosting issues are outside our scope of support. You'll want to work with your server administrator to resolve the issue here. Please ensure that the directory which the Invision Community software is in, is the correct PHP version/instance that you're looking at there on your server. You'll want to use the requirements checker at the link provided to review these items and work with your server administrator.
jwdenzel Posted June 1, 2022 Author Posted June 1, 2022 The site is hosted in AWS and I'm the sole administrator with full root access to the LAMP instance. All 3 of the following locations indicate I am using PHP 8.0.19: phppinfo() page IPS4.php that you linked to And my IPS Support page dashboard (screenshot) I can install any package that I need to, but I believe I have them all. Kindly asking for guidance from anybody. This appears to be a critical error and I don't want to permanently damage my site.
Solution Stuart Silvester Posted June 1, 2022 Solution Posted June 1, 2022 It's possible that you're using a different PHP version/install on command line to the web server. It would be worth checking that /usr/bin/php is the right executable. jwdenzel and shiobi 2

I updated the CLI to use 8.0 and the maintenance script ran without error. Thank you both @Stuart Silvester and @Jim M shiobi, Stuart Silvester, Mark H and 1 other 4
