Dear mitchoyoshitaka,
from me – also at first: Thanks a lot for this plugin. I have just started working with it and tuning it.
This is also my problem:
No pagination WITH the YARPP plugin activated. Only the first page until the page break is shown.
When I deactivate YARPP the pages are shown perfectly.
You say to check the php error log. Do you need that to reconstruct this error? If yes, how can I view this error log?
