Dear Machform Team,
After long time use of the form, we've encounter this problem recently. We can export to Excel but when we open the file, its contain unrecognised character and cannot be read. I've tried to look for the answer & found the post around 8 years ago when PHP iconv extension need to be enabled.
Asked my hosting provider to enable it, and it is enabled now. But the problem still persist. Appreciate it if the team can help me on this matter
