I had to copy relevant files from an existing joomla application to a fresh joomla installation. After doing that, some plugins and modules that were working properly on the old installation aren't on the new installation. e.g
I have {chronoforms}Contact_Us{/chronoforms} that is meant to display a contact form, instead if justs echos {chronoforms}Contact_Us{/chronoforms}.
I also have {module _Story_Player} that is meant to display a allvideoshare video but instead just echos {module _Story_Player}
When i access the backend to view these plugins, i get a 500 - An error has occurred with xml missing note, eg, for chronoforms, i get The file chronoforms.xml could not be found although I have all the necessary files copied to the right location.
I have looked through jooomla forums and other resource sites but havent found any pointers so far.
