Hi, Update.
I migrated the site to latest version over weekend. Now working well.
I took advice from this topic in the forum:
(essentially went through each version step by step until latest).
Notes:
The only folder you need to worry about is the htdocs one, and use Filezilla to overwrite them each time in Siteground. (Back up after each iteration after checking it is working).
The file permission issue that the SG tech said may be an issue, wasn’t, it all worked very smoothly.
To watch out for; the NEW dolibarr didn’t ‘like’ staying on the old PHP version, so make sure to upgrade to the new one after you have made all the upgrade steps.
Hope this helps
Joe
