I was sure I hadn’t changed the table prefixes, but actually I installed a security plugin (WSD security) and that did change them after I installed Form Manager. That might be an issue for anyone else using that plugin. Thanks for your response, I’ll change the tables manually as you suggest.
I get this error in 1.6.33, after updating WordPress to 3.3.2. The exact message I get is:
Plugin could not be activated because it triggered a fatal error. Table ‘educatio_wordpress.wp_fm_data_1’ doesn’t exist
I’m guessing it’s trying to create a table prefixed by wp_, but my tables aren’t prefixed with this. I tried re-updating WordPress and reinstalling the plugin. Any ideas on what else I could try?
