1th Step: Check for template files in the corresponding template folder
In general, view the Catalog phpcms/templates/default[template style identification]/content
Column Homepage Template: Start with (Category_), category_xxx
Column List page Template: Start with (list_), list_xxx
Content page Template: Start with (Show_), show_xxx
If the template file exists, look at the second step.
2nd step: See if the template file in the folder contains the Chinese
Example: Category-copy. html
Note the template file name cannot be in Chinese, because when you get a list of template files in the background template settings, this part is assembled into an array and then Json_encode () output,
If the JSON object is in Chinese, the final result will return NULL, so the list of template files for the drop-down menu is empty and will not be displayed naturally.
Solve Phpcms template settings can not display the column home templates, column list page templates, content page templates and other drop-down menu options issues!
