Failure to convert PPTX for within page view.

There appears to be certain content within a powerpoint that can cause the converter to fail resulting in the following log. User reports the following on a 2 page PPTX:

step 1 - remove images on both pages

step 2 - remove page 2

step 3 - add images back on page 1

only step 2 (1 page and no images) worked

Perhaps, you are encountering one of these bugs:

- https://jira.atlassian.com/browse/CONF-16086

- https://jira.atlassian.com/browse/CONF-15721

Try to save the file as .ppt and see if it makes any difference. It appears that Confluence Office Connector plugin handles .ppt better than .pptx

I followed instructions to clear various cache directories, and that seemed to do the trick.

Please can you provide the link to the instructions you followed
