I have the exact same issue, though I am unable to fix this with a backup file.
This is the content of the file, nothing wrong IMHO:
// Version: 1.1; Modifications
// Begin Auto Embed Media Pro Text Strings
$txt['mediapro_admin'] = 'Simple Audio Video Embedder';
$txt['mediapro_settings'] = 'Settings';
$txt['mediapro_save_settings'] = 'Save Settings';
$txt['mediapro_err_cache'] = 'Cache folder not writable must fix for performance!';
// END Auto Embed Media Pro Text Strings
Anybody have any clue to where the error comes from?
8: Use of undefined constant php - assumed 'php'
Bestand: /home/bodypro/domains/bodypro.nl/public_html/forum/Themes/default/languages/Modifications.dutch-utf8.php (init sub template - eval?)
I even replaced the mod file with the original english file (which is empty) and I got the exact same error.
Any comments are greatly appreciated.
