Sorry you're still having problem. As the error is indicating, the problem has to do with the .TPL file - which is a template file. You should make sure that the theme files are present. As per the error above, it's looking for "helpers/tree/tree_node_item_radio.tpl" and that file doesn't exist in that path. If you hosted this site in the document root folder as opposed to a subfolder, then you will have many problems with the path. Currently, the error indicates that you're running it in subfolder labeled "loja". If this differs from your previous host, then you will need to make adjustments to the configuration. You should also turn OFF friendly URLs until you can get everything working normally.
I hope that helps to answer clarify the issue. Please let us know if you have any further comments or questions.
