We have been using phpdox successfully for about a year now with no problem. Our application allows users to upload .docx files containing variables/tags that get replaced with actual data from a database. Our users and testers have created the original .docx files using Google Docs, LibreOfiice, and various versions of Microsoft Word. Nobody ever had a problem until now.

Today we got a .docx file that will generate the error shown below. I personally use LibreOffice so I immediately opened the file using LibreOffice on my MacBook and started looking for typos or any strange formatting. I didn't see anything odd so I simply saved the file without making any changes. The new file worked perfectly.

I tested this three times now with the same result. The original file generates the error below. Opening the file in LibreOffice and not touching anything before saving it makes a file that works properly.

The phpdocx code isn't very complicated. All we do is this:

$docx->replaceVariableByText($accountvars);

$docx->replaceVariableByText($jobvars);

$docx->replaceTableVariable($lineitems);

$docx->createDocx($name);

Can anyone tell us what the error message below really means? Any idea what could be wrong with the original file? We hope to find a way to identify the "bad" file and give the user a graceful error message.
