Hi,
My system is running on SuiteCRM 7.12.6. It is a fresh installation but it seems that I cannot upload excel (xlsx) or word (docx) files under each module.
I can upload documents like xls, doc but no xlsx and docx files types.
What could be the issue? Thanks
That is pretty weird. I just tried that test case on a 7.12.6 (uploading a docx under a Note record) and it worked like a charm.
Maybe there’s some other software interfering - some browser security, an antivirus, or some other network security device.
EDIT: you can also check file size. Maybe it’s not the extension that causes it to fail, but rather if these files are larger than others and exceed post_max_size or upload_max_filesize in your php.ini settings.
Hi, I have two installations with 7.12.9 and by one installation I have the same Problem. I have fuggure out, if the Filename ends with extention .xlsx and .docx I’v got an HTTP ERROR 500.
So I can fix the Problem when I disable the Module “Documents” in the Search Settings. But this is not a graet solution, cause the search work not with “Documents” any more 
There are explicit security restrictions to loading uploading those kinds of files.
It is configurable. Search these forums
I’ve run into this before. It might be that SuiteCRM isn’t set up to accept those newer file types (.xlsx and .docx) by default. You can try checking the allowed file extensions under Admin > System Settings. You might need to manually add .xlsx and .docx to the list of permitted file types. Also, sometimes the issue is with the server settings (like upload file size limits).
I did not find that setting under system settings.
If adding the file extensions doesn’t work, it might be worth looking into the server configurations. If you find that it’s an issue with Office file compatibility, getting the latest version of MS Office could help. Nerdused is a good alternative that offers good deals on Office subscriptions.
Check out your allowed MIME types in cpanel hosting (or whatever hosting environment you’re in).
