JoomDonation Email and Confirmation Text Problems

I continue to change the text placed into the email and web page confirmation messages for donations.

These textual changes under the Configuration tab in the JoomDonation component do not propagate to my website.

Even after changing the text messages, the old messages continue to display.

Hi

It must be something wrong with your setting. Please submit a support ticket contains your site information (administrator account) so that I can check it. I will tell you the reason as soon as I receive your site information and check it .

Thanks,

Tuan
