Something has happened

. Sometime over the last month my website has stopped displaying my monthly records.
I hadn't changed anything. Since then I have upgraded to Cumulus to the latest 1.9.4. It was running 1.9.3 when I first noticed it.
When I look at wt_month_inc.php the only month which is populated in June. No other months have any data
Index_txt.php is running at ver 1.2
I have checked the monthly data in Cumulus and it is all currently correct.
One thing I have also noticed is that the version number showing on the web page is not updating so there appears to be something wrong with updating he page (showing 1.9.3 when I am now running 1.94)
