Other Information

Same as this post and many others. Meta crawler cannot access site. I understand that this is due to a security mechanism implemented by InifinityFree.
Meta crawlers (as well as Google and others) are probably used by almost everyone on this platform. I would like to assume that these crawlers aren’t blocked without repair. If they are, the website will be severely crippled. Is this a limitation imposed on purpose, to promote account upgrades?

I have tried to tweak the .htaccess file. This actually affected the crawler, which resulted in a 500 error code. This still isn’t the expected 200 code so I’ve undone the changes to .htaccess

Any suggestions?
