I have a few issues with making my own custom theme, and against the documentation, I deleted my custom theme directly from the files. There is a good explanation of how to fix this issue here.
Many answers for the
"theme_dir" issue states to delete some entries from the
theme table in the Magento database, however in my Magento 2.2.5 Installatron I installed it from C Panel's installation two days ago & it has no such table in it. Does anyone know the new tablename that might be its replacement?
Thanks a bunch.
