Menù--Other Instruments---Delete Data----Files and Images Cache ( or similar, i have in Italian and don't know exact translate in English Menù )

I solved in this wa

After disabled all extensions and OperaTurbo the problem remain. So i clear the cache of Opera ( i made with WiseCare365 but think can use the Option in Opera ). After this i reload page and all was ok. Also re-enabling all extension now all working good.

As main problem are the files in the Cache maybe possible to avoid the step Disable Extension/Re-enable Extensions

Wow Terence. Tried to open same page in Private Mode and the website is displayed without problem.

Will try to disable all extensions. Will let you know...

I have a couple of Plugins installed ( have to check tomorrow as upgraded Opera only in my Office Pc) but i used same Plugins with Opera42 and all working good.
I tried also to disable Turbo mode but problem still remain.

After upgrading to Opera 43 version some websites renderized with some error.
This problem is not afflicting all websites.

Here some screenshots of same website with Opera 42 and Opera 43
