I have installed the latest version of Magento2.2.5 without sample data using XAMPP. Now I am trying to install a free third party theme from Venus themes.
app folder from the free theme folder and pasted it into root folder of my Megento2.2.5. upgrade. But still I am not able to find & select the theme from the admin panel of Magento.
In Magento everything works first with the registration & the declaration so first check that your theme contains the registration.php & theme.xml file at the below location
magento_root/app/design/frontend/Vendor/theme
Now just run the below command for registering & installing the setups for your theme into your magento.
php bin/magento setup:upgrade
Now go to the admin panel after login go to the below location from the left navigation menu
content > design > configuration > store/website
Select the store & then select your theme from the drop-down that you have just installed & save it & run the below commands now for the data deployment.
php bin/magento setup:upgrade
php bin/magento setup:di:compile (you can avoid this)
php bin/magento setup:static-content:deploy
php bin/magento cache:flush
Now you can refresh the front-end for testing the theme
Note: At the time of development change your magento mode into the developer mode with the below command
php bin/magento deploy:mode:set developer
Confirm the theme copied to the correct place.
<Magento root dir>/app/design/frontend/YourTheme
If theme copy correctly as per given path, Run below command and check again.
php bin/magento setup:upgrade
php bin/magento setup:static-content:deploy
php bin/magento cache:clean
Then Run all commands:
php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento setup:static-content:deploy -f
php bin/magento cache:flush
