Hi Adele,
thanks for using MH Magazine lite.
It seems there definitely is something wrong on your site because your layout is broken when using the search function. If you’ve modified any code, please restore the original codebase and you also may want to update your theme to the latest version because you’re using a very old and outdated version.
In case your issue still remains after updating to the latest version of the theme, then please do some further troubleshooting (e.g. disable plugins, etc…) to find the culprit on your website: Troubleshooting in WordPress.
Thank you for the reply. I tried to update the theme once. The whole page broke of it because the measurements of the pictures changed. I cannot edit all header pictures. So, I would like to stay with the old theme version.
I can’t remember editing any code during the last weeks (I don’t know how this would work).
Maybe, I could try to install a search plugin.
You need to regenerate the thumbnails after the update. But of course that will only work if the originally uploaded image has decent size. Here you can find more information about the sizes: Image dimensions in MH Magazine.
Regarding the outdated theme you’re using, it’s really very old and possibly also not fully compatible with WordPress anymore. It would be highly recommended to update your site and make it ready for newer version of WordPress.
