Can Someone Help with Error?

I'm having the following issue with my website:

When I click on a member, I get this error:

Fatal error: Call to a member function isAllowedDonate() on a non-object in /public_html/templates/base/scripts/BxBaseFunctions.php(131) : eval()'d code on line 1

Any thoughts on how to fix it?

Ran a search, and "isAllowedDonate" is nowhere to be found in vanilla Dolphin. This looks to be from a third-party module, in which case, I recommend contacting the developer. The function name should be a clue.

Are you using the Membership Donation module from the Market?

Thank you for the insight Nathan.

After your comment, I was able to locate the issue!
