hey everyone - good evening and thanks for all the support. i did as above - and no joy… i contacted the server people- and they reset permalinks and refreshed memory - etc… - but nothing worked.
i reset the plugin - to default - and no joy.
then out of desperation i spoke with booster for woocommerce guys. . and they were very very helpful . . ( even though im not a pro member ) - and on review - it turns out the problem was a conflict with my credit card - ( VISA ) - people - where i use Braintree by Paypal . . ( i also use paypal dirdct for paypal only )
the error showed up intermediately on google inspect . . so now my vat validaiton works perfectly - thanks to all - now i iwll raise the issue with Braintree - so all a happy ending on this saga ::}
hope this helps anyone else - in a similar fix . .
ps . . ( when i truned off the plugins to test - i did not turn off briantree - as its critical for my site to take visa - and never in my life would i have thought it would be the problem . ) - cheers have a super day ::}}
