I dont know if this has been mentioned previously or not, but in trying to install DPU, I kept getting a complete site crash on upload. Setting DPU Status to False had no effect on this. I personally am just begaining to learn PHP, so I have no idea as to what incompatibilities I should be looking for, however I do know how to narrow it down to what files in general are the problem-causers.

For referance, I am running Zen-Cart 1.5.5d, and DPU 3.0.8.

Includes > auto_loaders > jscript_dynamic_price_updater is causing the entire site crash. Removing it alone made everything run again, but I'm FAIRLY certain it's an important file to have. This did leave me with compleatly blank screens however, when I went to an actual product discription page.

Removing Includes > modules> pages > product_info > jscript_dynamic_price_updater fixed the white-page issue, but it doesn't matter, as with those two files removed, the module wouldn't work in the first place...
