DivaVocals:
It's unlikely that an incompatible Zen Cart add-on would stop the upgrade process. An add-o that is not v1.5 compatible;e will simply just not work or work correctly.. So instead of GUESSING it's best that printchic check her error logs instead so the EXACT issue can be evaluated..
Hey there!!
Just so you know, I had the exact same problem upgrading from 1.3.9 to 1.5.0, and it WAS a conflict with one of the mods. I could not gain access to my admin - just a blank page.
This is what I did after I could find NO alternative solution:
**og=original
db=database
1.Backed up my 1.3.9 database & made a copy of the sql file from an export of the database I had done via phpmyadmin.
2. Made note of all the pages I had changed in my og version (1.3.9). Luckily it wasn't hard since as I was designing I had kept a separate file on my machine labeled MyUpgrades - this had all the files I had altered, along with the mods I had installed and my changes to those mods.
2. Did a fresh install of of 1.5.0.
3. Made a back up of the brand new database & made a copy of the sql file from an export of the database via phpmyadmin.
4. Used WinMerge to identify the differences in the databases to make sure any imports into the new db from the old db would not have syntax errors (different tables names etc.)
5. Found the tables within og db (1.3.9) that contained my data - i.e. zen_products, zen_products_to_categories, etc.
6. FROM THE 1.3.9 sql export file I had made I found the 'zen_table_name' 'Dumping data for table zen_products'. I then copied ALL the 'INSERT INTO.....' from that section ONLY and pasted it into the sql section of phpmyadmin in my NEW DATABASE - this is fine so long as the TABLE NAMES MATCH.
7. Do this for any sections of your site that have data - you might also have to check within phpmyadmin to make sure that Indexes within each table have been properly copied into the new database as well.
**This is tough to do if you don't have any experience with phpmyadmin, but if you're resilient enough there is plenty of documentation online to teach it to yourself.
- Once I had the data from my og db copied into my new db, I then proceeded to update each file I had modified - via ftp from my MyUpgrades folder.
- I verified each mod I had installed was 1.5 compatible. Some things you might have to live without for a little bit like Image Handler. Hopefully this will come SOOOON!!!
***DO ONE STEP AT A TIME so it's easier to fix things if they brake.
This was my first upgrade and it was the BEST learning experience EVER. I now know that when there is an upgrade, DO NOT RUSH INTO USING IT until you verify ALL THE MODs you rely upon are compatible.
This is one area that the ZenCart documentation could use improvement. As a new user, you just think 'Cool, let's upgrade - it's safer, better security etc.' . But it's not clear (yes, it says, back up and uninstall your mods) but it doesn't say that your old mods will prohibit your new db from working.
It's cool. The learning process is good for everyone and the zen cart contributors are amazing and answering forum posts and providing their insights/knowledge & tools for free. Love 'Em for that!!!
