GZip Compression Monster Template Theme 55486

Hi,
gzip is not working properly:
I have followed the suggested route of checking with my hosting company, deactivating plugins to ensure there is no conflicts, then inserting the code into the htaccess file. My score increased to 69 from 34. I then used WP Smush Pro, the gzip is not working properly: message appeared again and my score went down to 33. I then deactivated WP Smush to see if the score would change or if the gzip is not working properly: message would go but it didn't .

Please help!
Philip
