phpmyadmin import sql error

[spectre]

I get this when I click on import an sql file in phpmyadmin before starting import process:

Warning in ./libraries/plugin_interface.lib.php#551
count(): Parameter must be an array or an object that implements Countable

Backtrace

string '',
)
./db_import.php#43: PMA_getImportDisplay(

Any ideas what's gone wrong in this?? Using CentOS 7 if this shortens formalities!
