when we use a nonmarchent gateway, the callback/return page redirect to received page, if a error is set by the gateways, blesta show the error message with a non well design panel box above.
also the panel box is not 100% width. we are testing in blesta 5.0.4
we have a plugin that is doing this out of the box, multi-languages plugin. you can check it in live in our website
