+
+<p>We recommend that you configure PHP with a higher limit if possible, like 40M.
+   There are several ways of doing this that you can try:</p>
+<ol>
+<li>If you are able to, recompile PHP with <i>--enable-memory-limit</i>.
+    This will allow Moodle to set the memory limit itself.</li>
+<li>If you have access to your php.ini file, you can change the <b>memory_limit</b>
+    setting in there to something like 40M.  If you don\'t have access you might
+    be able to ask your administrator to do this for you.</li>
+<li>On some PHP servers you can create a .htaccess file in the Moodle directory
+    containing this line:
+    <blockquote><div>php_value memory_limit 40M</div></blockquote>
+    <p>However, on some servers this will prevent <b>all</b> PHP pages from working
