Today I was working on a client blogspot to wordpress migration and client had whooping 3000+ post. For the migration there are some changes which needed to be make in php.ini to make sure that wordpress will be able to transfer all the blogspot posts and comments.
Though migration was successful after 8 hours of work but after installing few plugins 
dashboard was showing an error message stating :
Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 71 bytes) in /home8/xxxxxx/public_html/wp-admin/includes/misc.php
The problem was due to allocated memory size in php.ini file and the best possible work around is to change the memory_limit of your php.ini file.
Access your wordpress file using any free FTP account. On the root of your wordpress installtion, there is a file call php.ini.
Download the file and create a back up. Now edit the php.ini file and search for line
memory_limit = 2M
It can be 8M or 16 M
Change the limit to 64 M and it will look like
memory_limit = 64M
Now upload the file and check your wordpress dashboard. This should resolve the problem. If you still face the problem, Let me know and I will try to find the alternative solution.
In case if you don’t have access to php.ini file, ask your web host Customer care to change the memory_limit of your php.ini file.
I hope this will help others who will get into similar kind of problem.
