Hey,
Think we need some more info!
- What version of SuiteCRM are you on?
- What version of PHP are you using?
- What sort of hosting are you using? ( Linux-based(ie: cPanel) / Windows-based (ie: IIS)/ Localhost )
- Have you checked either the SuiteCRM.log or PHP error logs? Do anything of note appear in those?
(500 errors are typically server-side, so depending on your web server, you might be able to look into Server error logs too) - How many records are you trying to export? Is it a large number?
If so, it might just be a timeout error, and can be resolved by changing some php.ini values - Do you get this error anywhere else in the system? Or on other reports?
I’d found a few threads wherein some users detail the same issue, with some proposed solutions
(Such as changing php.ini values)
Might be worth looking through these?
