2.1 installation issue...

Hello, after grabbing the latest version and putting it onto my server (with the previous database), I've received the following error: The website encountered an unexpected error. Please try again later.Twig_Error_Loader: Template "profiles/opigno_lms/themes/contrib/platon/templates/system/html.html.twig" is not defined. in Twig_Loader_Chain->getCacheKey() (line 129 of /home/piyon/o21c/vendor/twig/twig/lib/Twig/Loader/Chain.php). When I run update.php I also receive this: The website encountered an unexpected error. Please try again later. RuntimeException: SplFileInfo::getMTime(): stat failed for profiles/opigno_lms/opigno_lms.info.yml in SplFileInfo->getMTime() (line 155 of core/lib/Drupal/Core/Extension/Extension.php). I believe it has to do with my previous db content... any clues how to continue?

2.1 installation issues

you are updating Drupal Core, and what you did is not the right procedure. how did you install Opigno the first time? Composer? Drush? or Just download the file and placed in your web root?

thanks, just threw away the

thanks, just threw away the troublesome install and started with composer. the trouble was probably some misconfigurations of previous modules etc affected the later release (it gave template errors and such). thansk for questioning, which led me to composer install, which is much easier now. :)
