How To Turn Off Emails From Facebook Groups.
I was asked by various Facebook friends, and people within the new Facebook groups (updated version of groups) how to turn off their automated e-mails letting them know of every post and update made. Rather than repeating myself I thought I would knock up a quick tutorial, here it is. 
Updated From MyLinks To imLinks And Now Broken Screenshot Images? ImpressCMS – A Quick Fix
I just did an update from Mylinks which is a very out of date old XOOPS module and it went relatively smoothly which I was surprised, well except one very minor thing
If you are not sure how to go from Mylinks to imLinks, its pretty easy.
First grab yourself a copy if WF-Links 1.06 from http://members.chello.nl/rengelsman/mcdstore.html and upgrade to that, there is an update script with instructions in the read me. Once done then download the latest version of imLinks, you can get this from the ImpressCMS addons website. Again there is instructions on how to upgrade from WF-Links from the read me.
Now, I don’t know why but after updating the module as instructed to do through the read me and auto updater I find that in the database there are a ton of empty screen shot fields which generates a dead image on the front end for your viewing public. This is because the script detects a blank space and tries to parse it as a link to a screen shot image. To fix this just log into phpMyAdmin and run the following MySQL code
UPDATE `DATABASE_NAME`.`PREFIX_imlinks_links` SET `screenshot` = '' WHERE `PREFIX_imlinks_links`.`screenshot` = ' ';
Don’t forget to change the DATABASE_NAME to that of your own and the table PREFIX to the one you use in your database. Once done and run you will find no Screen shot column has this space and thus the problem is solved. Simples!
As I said, I don’t know why it happened for me, perhaps something in the good ole days, maybe the upgrade itself which I doubt but still possible but if it happens for anyone else, then here is your fix!
Thank to McDonald for making the awesome imLinks what it is today!
Disabling Your ImpressCMS or XOOPS Modules from PHPMyAdmin
Ok, so you’ve started to upgrade your CMS and you’ve found that your hitting issues, well this could be a number of reasons for example it could be a module you installed on your website. Weblog and various other modules have been issues for me in the past. WordPress actually disable and then re-enable all their plugins for you to prevent potential code clashes causing you issue. ImpressCMS and XOOPS however don’t or at least XOOPS didn’t on the last version I used before upgrading it to ImpressCMS which was 2.0.18.
Anyway, so if you’ve already overwritten your files with the new upgrade and your presented with a white screen or you having bodged upgrades then chances are its a module. First of all make sure you have a back up of your installation (which you should have from before the white screen and upgrade issues), reinstate your database to the back up (the bodged upgrade could have altered the tables). Log into your PHPMyAdmin or equivalent and then run this MySQL code.
Update table_modules SET isactive = '0' WHERE isactive = '1'
Make sure that this “table_modules” is changed to your table, so if its “mysite_modules” then put that other wise this won’t work.
MySQL Disable ICMS And Xoops Modules
Hit the go button and now all your active modules will be deactivated, now try your website and upgrade, hopefully this might have solved the issue for you. If it does, then only activate your modules one by one to find out which one was the trouble causer.
