Hi Seyi,
Nothing critical, just noted the following warning when upgrading AwoCoupon to 2.5.5:
Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; awocouponInstall has a deprecated constructor in /home/xxx/public_html/tmp/com_awocoupon_update/install.awocoupon.php on line 51
Using PHP7.0.15
Regards,
Chris
