I am using the completely free version of Odoo Online, I found that the free features are enough for my e-commerce website but out of curiosity, I went to the application section to try to install some paid applications. I thought I could remove them and everything would go back to the way it was without them but no.

I removed all those applications, however, my interface kept showing "Your trial will expire in 13 days. Enter your subscription or buy a subscription.", not only that, some information was completely messed up. How can I remove this trial mode and restore the database to the way it was before the random installation.

Thank you very much for your support!
