Remove Theme Files
1. If you can find the theme files in the folder
then remove these folders. Also, you can remove other Magefan modules you don't need in the app/code/Magefan.
2. If the theme was installed via the composer and its files are located in the folder
then run the composer CLI command to remove it
composer remove magefan/theme-NAME
# replace NAME with:
# frontend-optimized - for Optimized Magento 2 Theme
# frontend-optimized-plus - for Optimized Magento 2 Theme Plus
Once extension files have been removed, run these Magento CLI commands:
php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento setup:static-content:deploy
Remove Theme Data (optional)
Attention! This will clean all Optimized Magento 2 Theme logs and settings.
1. Just in case please make a full backup (dump) of your Magento 2 database.
2. Run the next MySQL queries to remove the data. E.g. you can use phpMyAdmin for this purpose.
DELETE FROM setup_module WHERE module = "Magefan_ThemeOptimized";
DELETE FROM `patch_list` WHERE `patch_list`.`patch_name` LIKE '%Magefan\ThemeOptimized%'; DELETE FROM core_config_data WHERE path LIKE 'mfthemefo/%';
