We see that your website doesn’t work at all because of lack of PHP memory limit. We get this error Fatal error: Allowed memory size of 75497472 bytes exhausted
You need to contact your hosting providers and ask to increase the following parameters:
PHP memory limit to 256MB
PHP post max size to 64MB
PHP time limit to 300
PHP max input vars to 5000
Max upload size to 64MB
and it would be better to update your MySQL version to 5.6
