WordPress.org

Prerequisite

1. Starting from ScoreRender 0.2, PHP4 compatibility is dropped, and PHP5 is strictly needed.
2. Starting from ScoreRender 0.2, ImageMagick >= 6.3.6-2 is needed, due to usage of -flatten option.
3. Music rendering programs must also be installed on the same machine web server is running. For example, to support Lilypond fragments, Lilypond >= 2.8.1 must be installed in web server. Refer to installation page for more detail.

New install

1. Install any prerequisite programs as noted above.
2. Extract archive, and copy 'scorerender' folder to wp-content/plugins/, keeping the folder structure intact.
3. Login to WordPress and enable the plugin in admin interface.
4. Configure ScoreRender under the ScoreRender tab of the Options page.

5. In Option -> Writing, check if this option is turned on:

   "WordPress should correct invalidly nested XHTML automatically"

   It must be turned off if you intent to render Lilypond and Mup fragments, since this option will convert "<<" and ">>" into "< <" and "> >" correspondingly, thus destroying the music content and cause render error.

Upgrade

1. Deactivate the plugin in WordPress admin page.
2. Remove the whole plugin folder.
3. Upload new plugin and activate again.
