Recently updated to WordPress 4.9.9 or 5.0.1 and your CSV file imports for Store Locator Plus® stopped working? It is now fairly common to see a “file type is not permitted” error when uploading files. You can thank yet another “WordPress security feature” — also known as “backwards compatibility break”. This “update” came with absolutely no warning to plugin developers.
