Google Webmasters – Search Appearance – HENTRY errors

Hi – I have about 700 Hentry errors and after reading about it it seems to be to do with a poorly constructed theme files. StackExchange state:
This issue is rather common and found in mostly poorly edited or made WordPress themes. entry-title, updated and author are all related to the Hatom markup which requires hentry to included above the fold and ideally in the body.
It’s likely that your website is missing author, updated and entry-title leaving hentry still within your code. View source and check if you can see ‘hentry’.

On my site one of the pages throws up 45 errors – the testimonial page – this is a standard page with a Masnry Element containing approx 45 portfolio items. I suspect the 45 errors are one for each of the testimonial (each testimonial is a portfolio item) items in the masonry element.

Another page – destination Galway (link below) throws 9 errors. This is an actual Portfolio Item Page – but liketh etestimonial page above it also has 3 masonry elements – 2 of the elements displaying portfolio items (the other displaying product items)..

It seems that the portfolio page files in the theme are what is causing the issue.
Any quick fix…
