Hello, kirsii!
Sorry for the late reply, we are don’t work on the weekend.
The Agama theme should work well with the woocommerce.
The issue you describing can be caused by some other plugin(s) you recently activated.
Please try to deactivate all plugins except the woocommerce to see if that helps.
If the then the website works normally, activate the plugins one by one until the problem reoccurs, so in that way you can find the problematic plugin(s) if any…
Also, make sure everything is up to date.(update the theme/plugins)if needed.
If you try this and still no success, please give me your admin Username/Password in the private reply, so I can check the issue directly on your website.
Thank you.
Regards
