Error requiring /typo3conf/ext/direct_mail_subscription/fe_adminLib.inc
I get the following error when upgrading wt_spamshield on an older TYPO3 instance:
Fatal error: require_once(): Failed opening required '/home/.../public_html/typo3conf/ext/direct_mail_subscription/fe_adminLib.inc' (include_path='/home/.../public_html/typo3/contrib/pear/:.:/opt/php-5.5.21/lib/php') in /home/.../public_html/typo3conf/ext/wt_spamshield/ext_localconf.php on line 77
If a particular direct_mail_subscription version is required, it should probably be noted in the ext_emconf.php file. Currently there is no dependy on direct_mail_subscription at all in ext_emconf.php
I was able to work around this bug by creating an empty /typo3conf/ext/direct_mail_subscription/fe_adminLib.inc file.
