I have just moved my site to a new server and most of the settings in admin are are missing. I have checked the database and the settings are there, I have also changed the references to the file path info/URLs in the database. The site itself is working showing event data.

Hi Mark,

When you changed the references to the file paths and URLs in the database were the indexes for each serialized string updated to match the new serialized string length?

If not, these are a few tools that help automate this process when moving servers/domains:

Hi Josh, yes I use the interconnectit script to change my file paths and URLs. I enabled the requirements plugin and saw some warnings. Could it be related to MySQL or PHP version or module?

I suppose it’s possible if it were moved to a server that did not meet the requirements to run Event Espresso, but I do not think it’s likely.

Which settings pages are blank? Do you have a copy of the original db before the change to compare it with?

All of the settings pages are blank, apart from the Events Overview page. I have both databases, what should I look for?

You can look for differences in the values in these rows in wp_options:


You can also verify that the database prefixes match up with what is set in wp-config.php.

Hi Josh, I can’t see any differences between the values in the fields. Anything else I can look at?

A fresh installation of Event Espresso’s files may help.

Hi Josh, the upgrade of the plugins did the trick. Although in the side bar under From the Blog I get this error:
Fatal error: Out of memory (allocated 41418752) (tried to allocate 1966080 bytes) in /websites/123reg/LinuxPackage21/ol/ev/i_/ on line 2736

If you are running out of memory at 41MB (per your error message), then you are going to have difficulty running WP with plugins that themselves need a significant amount of memory (such as EE). Our recommended minimum is 64MB, and for performance reasons 128MB or more is preferred. Check out this article in the WP codex,, and as it says there, you may need to contact your host’s tech support to get an increase. My own test site runs on a VPS with a guarunteed minimum of 512MB and can flex up to 2GB depending on the physical server load, and that only runs around $30 a month.
