I thought it was a bug in the message plugin but it turns out that it is the theme that I had purchased.  Previously the support had been great but now the author is refusing to update claiming that it is the store blocking him from properly updating his work.  Now he continues to offer his products for sale.

Whose fault is this?  I don't want to be too hard on him if it is a reported and un-repaired defect in the Oxwall store preventing him from supporting his themes.

What is going on?
