Here&#39;s a Drupal handbook page on the subject:<div><br></div><div><meta http-equiv="content-type" content="text/html; charset=utf-8"><a href="http://drupal.org/node/529866">http://drupal.org/node/529866</a></div><div><br>

</div><div><a href="http://drupal.org/node/529866"></a>I have never seen this happen myself, but it seems to happen when a variable is improperly serialized in the database variables table.</div><div><br></div><div>The solution seems to be to run one of the debug options mentioned on that page which will indicate to you which variable is acting up, and then fix it by editing the variable (either on the mysql command line or through a tool such as phpmyadmin).</div>

<div><br></div><div>If you still have the original database up and running, try clearing the cache, carefully reexporting the database, then reimport into a clean, empty database again, perhaps that will bring everything up better.</div>

<br>I searched the web, but didn&#39;t find anything that could help me. <br>Any suggestions on how to find the problem? <br>I am running drupal 7, and have listed the installed modules below. <br><br>Thanks, Ursula<br><br>
