V2.0.0 and Blank Sideboxes

Upgrading from v1.5.8 to 2.0.0.

Do the blank sidebox files still work with v 2.0.0?

Each time I upload the blank sidebox files to includes/languages/english/extra_definitions/YOUR_TEMPLATE_NAME/ my site brakes and I get
This page isn’t working is currently unable to handle this request.
HTTP ERROR 500

The blank sidebox files have also been uploaded to includes/modules/sideboxes/YOUR_TEMPLATE_NAME/
includes/templates/YOUR_TEMPLATE_NAME/sideboxes/

The above two folders do not brake the site when the blank sidebox files have been uploaded.

Thanks for any help

The mod does not list being compliant with 1.5.8 or 2.0.0. That does not necessarily mean it isn't but, with the language file changes in 1.5.8., that may be your problem.

If the mod contains language files, you may need to modify them to meet the 1.5.8 standard.

Thank you!
