[Show Quoted Text - 11 lines][Hide Quoted Text] Hi - just to follow up on this ... I did a clean install of the latest versions on a windows PC (apache 2.2.15, php 5.3.2, horde 3.3.8, imp 4.3.7). IMP is still giving me a blank window when select "view html in new window" on the attached message. I have tried it with tidy set to 'true' and 'false' in imp/mime_drivers.php, but no difference. The only messages in my PHP error log are warnings and deprecation notices, which appear for every page access so I don't think they're specific to this. I guess the changes in IMP 5 have fixed this, but it seems to be a problem for previous versions. FWIW, I can view this message just fine in IMP 4.3.8/Horde 3.3.9.

My guess is either that you are/are not using tidy (whichever one Jan isn't using), which is altering that message to a point that our HTML/XSS filter is stripping out the entire body of the message, or that something has been fixed since IMP 4.3.4. I can verify this displays correctly in IMP 5. The entire HTML sanitizing process has already been rewritten in Horde 4/IMP 5 from regex based to XML parsing - this should prevent issues like this from ever happening in IMP 5.

The message works perfectly fine for me. Please follow the hints at http://wiki.horde.org/FAQ/Admin/Troubleshoot#wsod to generate and find a useful error message.

Hi - Horde 3.3.4, IMP 4.3.4: attached is a text/html-encoded message which looks ok to me, and displays properly in Thunderbird. In IMP I see the text reasonably well in the message view page (although most of the formatting is understandably missing), but if I click "Show this HTML in a new window" it produces a completely blank page. Can you take a quick look at the attached message and let me know if this is a problem with this specific message or whether IMP is not handling it correctly? Thanks. -Robin
