[TYPO3] captions for images are gone after 3.8.1 -> 4.0.2 upgrade?

Thanks a lot for the response.

Yes, I checked the 'Update Wizard' in the install tool to make it really
typo3 4.0 mode.  After that, I removed the local cron_cssstyledimgtext
extension.  The captions come back now.  But the sizes and positions of
the images are not the exactly the same as they used to be.  In the master
TS template, we have

plugin.tx_croncssstyledimgtext._CSS_DEFAULT_STYLE >

And instead use,

page.includeCSS {
  ...
  file4 = fileadmin/templates/css/cron_cssstyledimgtext.css
  ...
}

I noticed the classes for images and text were changed from csi_blah to
csc_blah.  So looks like I need to find out the default style sheet that
css_style_content uses and make a local customized copy of it.
