Im having trouble with the Recent Ads block displaying in a line not in a 4x3 or 4x4 grid I usually display it in.
It was working before I upgraded to 5.4 and now it's not.
It happens both with VB Style integration and the built in PP Classifieds Style. Im also having trouble with the Calendar display in the sidebar. It displays at 100% width instead of within the sidebar.
That sounds to me like under your plugin does not have the correct database information.
Look at the error
Table 'dragon_class2.ppproducts' doesn't exist
Your telling us the classifieds table prefix is pp would it not be by default cp_ so I would suggest you disable the plugin and under the global variables plugin for classifieds make sure all the information under there is correct.
Also make sure under admin edit integration the table prefix has been answered correctly under there.
Same answer as I already posted above. Your table prefix for Photopost in the plugin etc would have to be incorrect. You need to make sure all the settings in both admin => edit integration as well as in the actual plugin which will be correct provided you follow the instructions. Make sure you read the upgrade documentation on how to install the plugins and try generating a new plugin. Make sure to uninstall any old plugin before you reinstall the new one.
if things where correct the classifieds tab would be highlighted and the classifieds menu shown in the vb sub navigation bar.
My suggestion would be to make sure your vb navbar template is not modified and that you follow the instructions in our upgrade or install documentation on how to do your xml plugins for vbulletin and reinstall those.
