Parameter 2 error when editing

When trying to edit an item with Firefox and Chrome, we are getting this error message repeated 12 times up at the top. I'm using FF 10.0.2 for Ubuntu, a colleague is using FF 10.0.2 for Mac, and I've also tested this with Chrome 17.0.963.56.

Warning: Parameter 2 to plgFlexicontent_fieldsTextSelect::onDisplayField() expected to be a reference, value given in /home/warnerpa/public_html/libraries/joomla/event/event.php on line 67

We can still edit so this seems to be more of big nuisance.

this is because of newer PHP version,

which FLEXIcontent version you have?

Errors went away once I updated back to 1.5.6. I think it may have been a result of trying to revert from 1.5.6 rc3 1151 to 1.5.5stable. See my other posts for details.

aaa i see, if you revert back to v1.5.4,

then after reverting back to v1.5.4, you will need to uninstall the new fields (joomla plugins) textselect and relateditems.
