Parse Error Started showing up from eForm

I have all of a sudden started getting a couple of messages a day about a Parse Error in eForm. The form is working correctly and I do receive an email when someone makes a request. So eForm seems to be working fine. With the amount of times and how frequently this has been occurring during the past several weeks, I am wondering if the site is being hit by bots?

I am not an expert with this but have had a similar problem in the past. I changed the manager character set to UTF-8 and that solved my issue.

• What version of eForm is in use
• What version of Evo is in use
• What charset is set in the manager (Tools => Configuration => Site Tab - Character encoding)

Check:

• If your server has been updated - what PHP version is in use
• If your database has been modified

Searching on this topic you will find that as of PHP5.4 the default charset for htmlspecialchars is "UTF-8".

If, in your manager, you are using anything other than UTF-8 that may well be the problem, so long the PHP version is 5.4+
