So i tried to install newly on bitnami wordpress AWS lightsail packages. * I’ve intalled and deleted several times. (about + 10 times…) * After i completed Handbook’s STEP 2 (write secret.txt file’s content on wp-config. php and remove directory /opt/bitnami/wordpress/wp-content/uploads/lmfwc-files), I met Error Message whenever adding license key. * I don’t know what causes this error. I just went through HANDBOOK’s instructions. * (2) * Because removing lmfwc-files directory caused error, So i don’t touch this folder in this time. I try to link product to license key. But i can’t because No product’s shown in drop-box. (i try to input some characters into drop-box, but i can’t.– In advance i added test product and checked the boxes – “sell license keys for this product”, “sell license keys from the available stock”, “Virtual” – Plus checked “Enable automatic stock management” on setting menu. also “click Syncronize”.) * I’m not programmer and I’m not familiar with php, wordpress. So… After installing, then i just tried to turn other plugin off or change theme. and try again…… All day. (I tried to turn off all other plugin except woocommerce and wp mail smtp, but it didn’t work / theme was NEVE and ASTRA in this test.) * i’ll be very glad for your help. thank you for your time. * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Ferror-when-adding-license-key%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 8 replies - 1 through 8 (of 8 total) * [M Haseeb](https://wordpress.org/support/users/haseeb0001/) * (@haseeb0001) * [3 years, 12 months ago](https://wordpress.org/support/topic/error-when-adding-license-key/#post-15628375) * Hi [@pacomini](https://wordpress.org/support/users/pacomini/) * Hope you are doing good. * Can you share the screenshot or video of the issue? or share the use case or steps then I can reproduce this on my staging website. * Thanks * Thread Starter [pacomini](https://wordpress.org/support/users/pacomini/) * (@pacomini) * [3 years, 12 months ago](https://wordpress.org/support/topic/error-when-adding-license-key/#post-15630786) * Thank you for your reply. * “Share steps” means how i did install my site?
